Alberta and Saskatchewan 2nd most radon-exposed populations

By News No Comments

Alberta and Saskatchewan 2nd most radon-exposed populations on Earth claims latest research 

A University of Calgary-led study has found that the Western North American Prairie provinces of Alberta and Saskatchewan are the 2nd most radon-exposed populations on Earth, just behind Poland. The study generated many interesting findings, one of the most concerning being that radon levels in North American residential environments may be increasing, with newer homes being the most susceptible to rising radon levels. The study was based on testing 11,727 residential buildings throughout Alberta and Saskatchewan. 

The study found that numerous property metrics contribute to indoor radon levels, including the year of construction, the size and building type of the home, ceiling heights, and the window opening behaviors of the occupants.  

The research incorporated multiple testing approaches, including long-term and short-term alpha track tests from Radonova, short-term E-Perm tests analyzed by AGAT Laboratories, and RadonEye continuous radon monitors manufactured by FT Labs. While short-term radon tests are indicative of radon levels during the testing period, the study also suggests they may not always coincide with a home’s long term average radon level, in particular short term tests performed in summer months as compared to a long term tests performed over winter months. The full report can be found here. 

The research team relied on data gathered from the Evict Radon campaign, a non-for-profit project where Canadians are encouraged to be “citizen scientists” and participate in the study by testing their homes and answering survey questions prepared by researchers. Through science, the campaign aims to eradicate radon exposure in homes to prevent future cases of radon-induced lung cancer. The study is open to all Canadians and people can register now. New participants will be accepted until February 29, 2020. To find out more, visit the Evict Radon website 

Weston Jacques, Executive Director of Evict Radon, said: “Radon awareness is very low. Not a lot of people know about it, or really understand it. What we’re really trying to do is leverage the University research to increase awareness and education about the harmful effects of radon. There aren’t many platforms which allow the public to ask questions about radon, which is a responsibility we’ve taken onboard.” 

Bill Rounds, President of Radonova, said: “The research findings will hopefully encourage communities and individuals to take action and test their homes for radon. Participating in the Evict Radon project not only provides researchers with valuable data to further understand the factors that contribute to indoor radon levels, but also provides participants with their home’s radon levels, empowering them to make decisions and take action with regard to their indoor air quality. Living with high levels of radon is an unnecessary health risk that can easily be reduced.”

Radonova launches ROBIN2 – a professional radon sensor with high sensitivity

By Measurement, News No Comments

Radonova Laboratories has launched ROBIN2, broadening its range of radon measurement technologies. The latest version of ROBIN is twice as sensitive as its predecessor and includes an improved response function for optimum compliance with rapid changes in radon levels.

ROBIN2 is a state-of-the-art radon sensor that can be deployed as a fixed installation in smart homes for monitoring and reducing radon levels. It can be mounted in all types of ventilation control units where there is a requirement to monitor radon levels. It can be easily connected to a controller, central unit, data logger, fan control system or PLC and is available in various formats.

The new response function improves measurement accuracy as radon levels fluctuate. This is due to its improved sensitivity, which reduces error at lower levels, otherwise it is limited by deteriorating statistics due to the pulse rate being too low. ROBIN2 has a new motherboard that is more insulated and weather resistant. ROBIN2 is available as a standard or industrial version which can be used for mining. The mining version has enhanced protection against dust and moisture and is optimized for underground measurements.

– I’m delighted that Radonova has enhanced the capabilities of ROBIN, which was the first radon sensor of its kind when it was first launched in 2016. ROBIN2 is without doubt a market-leading detector, due to its new response function and overall stability, said Dag Sedin, a senior advisor at Radonova, who was integral to ROBIN’s initial launch.

ROBIN2 is available now.

About ROBIN2

ROBIN2 measures the radon content of air in Bq/m³ and gives an analog output signal of 1-10V, proportional to the concentration of radon in the air. Compared to its predecessor, ROBIN2 has improved sensitivity and a larger and more efficient measuring chamber. The output signal is also more stable and more consistent with the real radon content variation. If required, the measurement range can be defined by the customer. The radon sensor is protected against electromagnetic interference and can be connected to a thyristor controller. The transducer is mountable without directional dependence and can be permanently installed in a room, ventilation shaft or air handling unit. The mining version has enhanced moisture protection and is built for an underground environment.

Additional features:
• Can measure accurately in both laminar and turbulent airflow
• High sensitivity to provide good time resolution
• Great flexibility and can be customized for OEM

Interview with Weston Jacques of Evict Radon

By News No Comments

In this Expert Interview we talk to Weston Jacques, Executive Director of Evict Radon – a new non-profit organization dedicated to radon awareness and testing across Canada via a University of Calgary research study. During our conversation, Weston discusses the evolution of the Evict Radon campaign and how it is expanding this year…

How did the project come about?

Evict Radon started as a research study out of the University of Calgary through Dr. Aaron Goodarzi. Dr. Goodarzi is studying radon at the University and trying to identify why some homes have low levels of radon, while others have high levels of radon. In order to do this, he needed as many people as possible to test their homes for radon gas. In order to do this successfully, he needed to build a campaign to increase public awareness with a call to action to purchase a radon testing kit, hence the creation of Evict Radon.

What is your role in Evict Radon and how has the campaign grown?

I was employed by the University of Calgary in November 2018 to support Dr. Goodarzi’s from a communications perspective and help get the message out there. My employment coincided with additional funding for the project which was used to widen the scope of Evict Radon outside of Calgary to the rest of Alberta.

Due to the success of Evict Radon last year we realized it had more scope than just a four-month campaign (October- January). It soon became apparent that Evict Radon could shape radon awareness, on the back of the University research, across the entire country. Therefore, in February 2019 we took the decision to incorporate Evict Radon as its own non-profit. This is when I assumed the role of Executive Director.

Even though we now have a national focus, we are still very much run out of the University of Calgary, but we recognize that we are growing and it’s becoming a much bigger entity than just a University research study. My role during the campaign season is to ensure the public understand what radon is and why they should purchase one of our kits and participate in our project.

Crucially, by purchasing through us you are contributing back to lung cancer research. Furthermore, the kits are analysed in a laboratory which is the only ISO17025 certified alpha track testing facility of its kind, so we are 100% confident in the lab analysis and its QA process.

Why does the campaign run during the fall and winter?

Originally the research was showing higher levels of radon in the winter – particularly in climates such as ours. Because we have very cold winters people seal their homes and turn on their furnaces which creates a shift in the negative pressure which in turn has the potential to increase radon levels.

What has been the feedback from the public?

Radon awareness is very low. Not a lot of people know about it, or really understand it. What we’re really trying to do is leverage the University research to increase awareness and education about the harmful effects of radon. As Dr. Goodarzi is the Canadian Research Chair for Radiation Exposure Disease, it provides the campaign with a degree of authority and so when we communicate with the public there’s a lot of trust as it comes directly from an institute. In general, the feedback has been really good.

Evict Radon was never meant to be a scare campaign, we didn’t want to freak the public out about a gas in their homes which they couldn’t see, smell or taste. We wanted the campaign to be easy to remember which is why we called it Evict Radon, it’s a play on words which is easy to understand and gets the message across.

There aren’t many platforms which allow the public to ask questions about radon, which is a responsibility we’ve taken onboard. You can find out a lot of information on our website and we try to keep it as simple as possible. We take the time to answer all calls and emails and reiterate this is the first step to lung cancer prevention.

What’s new moving forward?

In order to communicate our message across all of Canada, we need to offer all our information in both English and French. We’re currently exploring what it will take to develop a French website and French speaking support team. For this year, there will be far more focus on the Saskatchewan province in Western Canada as we are seeing very high levels of radon in this area and really hope to get as many people testing as possible.

What has been your experience with the service provided by Radonova?

We could not do this without the support of Radonova. Their partnership in this endeavor has helped us design a custom service model that meets the specific needs of our project. They’ve been fantastic in terms of accommodating our residential audience – each homeowner must fill out a home metrics survey and register their kit on Radonova’s platform. The research we produce annually couldn’t happen without this information and because of this, they have been a phenomenal partner in the success and expansion of the Evict Radon campaign.

Radtrak2® – the world’s leading detector for long-term radon measurement

By Measurement No Comments

With over four million units sold globally, Radtrak2® is the most widely used radon detector for obtaining a reliable and accurate annual mean of radon levels in the home or workplace. Here is a short summary of its features:

Simple, foolproof assembly

The Radtrak2 unit is simple to construct. Included is a plastic top and bottom as well as a transparent plastic film made of CR-39 which is placed at the centre of the radon detector. During measurement, air leaks in through a very small gap between the top and the bottom. When the radon gas in the air decays to radon daughters, radioactive alpha particles are created. When these hit the transparent plastic film, tracks are formed in the film. After the measurement period, the number of tracks is used to calculate the radon level.

Environmentally friendly and robust technology

Since the detector is made of plastic and there are no moving parts, the radon detector rarely malfunctions. Radtrak2 can be used in very demanding environments and is not damaged if dropped on the floor. It is very difficult not to get an accurate measurement when using Radtrak2®. As long as you specify the start and stop times and use an accredited laboratory, you are guaranteed a reliable result. Radonova’s laboratory is always reusing the top and bottom parts of the detector, saving both cost and the environment. The only thing that is not reused is the transparent plastic film which is used for analysis.

Clean plastic film and fine-tuned, accredited analysis

When analysing the transparent plastic film (CR-39), there are certain requirements and stipulations which must be met. Firstly, a clean film must be used, placing demands on the manufacturing process of the detectors. Without an original pure film, it is not possible to analyse the number of tracks accurately after the measurement period. You must also take into account how much radon gas the plastic film has been exposed to before it is placed and sealed in the detector. Similarly, you must make allowances for the film being exposed to radon when it is sent back to the laboratory. Through a carefully controlled process, the laboratory calibrates various plastic films against a known radon source. Well-established routines are necessary to mitigate against error. Therefore, always purchase a radon detector from an ISO 17025 accredited laboratory such as Radonova. At Radonova, quality checks are continuous, ensuring that the radon measurement is correct.

Why measure for radon?

Every year around 230,000 people die of lung cancer caused by radon exposure. Radon gas is part of the element of the uranium decay chain and since uranium is found in many places in the earth’s crust, radon is found almost everywhere. High levels of radon can be found in regions which have a large concentration of rock or have a cool climate. The latter is due to the fact that radon gas levels are usually high in insulated houses that are heated. To be fully aware of radon levels, homeowners should always measure.

Most countries in the world require measurements that provide an annual mean, which usually entails a measurement period of over three months.

The world’s most accurate radon detector for short-term measurement turns 20

By Home, Measurement No Comments

Radonova has been supplying Rapidos radon detectors for 20 years. In that time, over 250,000 units have been manufactured which have mainly been used for short-term measurements (between seven to ten days). This type of measurement gives a good indication of radon levels that may exist in the home or workplace. Normally, Rapidos detectors are used when you do not have enough time to take a long-term measurement and obtain an annual average – which requires a measurement period of at least three months in most countries.

High accuracy when compared to market alternatives

There are many types of radon detectors for short-term measurement. However, none are as reliable as Rapidos.

“Rapidos continues to be unique, not least because of its large chamber volume for detection and the clean, transparent plastic film that is placed inside the detector. After 20 years of use by customers from all over the world, we know that Rapidos remains the leading and most popular detector for short-term radon measurement”, says Karl Nilsson, CEO of Radonova Laboratories.

Rapidos consists of a plastic lid and bottom with a gap that lets in the air which is measured. Radioactive alpha particles arising from the decomposition of radon gas leave traces in the transparent plastic film made by C39. In order to obtain a precise measurement, it is crucial that you obtain sufficient traces of the film which can then be analysed, especially in view of the short measurement time. The large measurement chamber enhances the detection speed to provide an improved statistic for short-term measurement.

“Many suppliers use the same type of detector for both long and short-term measurement, which in all honesty does not provide sufficient accuracy. Detectors like Rapidos have too small a measurement volume for long-term measurement requirements”, continues Karl Nilsson.

Ideal to use when selling or buying a house

Rapidos is mainly used in relation to the sale or purchase of a property. In this scenario, you often don´t have time to wait for a long-term radon measurement. However, by using Rapidos you still get a very good indication of radon levels. The analyse provided is usually adequate enough to decide whether a radon-lowering measure is required. In contrast to long-term measurement (which is conducted to obtain an annual average value), short-term measurements can be done all year round. In many countries, long-term measurements are only conducted when the heating is on at home or in the workplace, which is normally between October and April.

Why measure radon?

Radon is a radioactive gas that leaks from the ground and in some cases comes from building materials. Depending on the ground beneath the house and the type of building construction, harmful high concentrations of radon can occur. Second to smoking, it is the cause of most lung cancer cases in the world.

Globally, an estimated 230 000 people are affected each year by lung cancer as a result of long-term exposure to radon. Lung cancer is one of the cancers that has the highest mortality, with only 20 percent of those affected surviving five years after the initial diagnosis. Therefore, it is essential to monitor for radon to ensure that it does not exceed the applicable national limit values. Note, limit values vary from country to country. However, if you order a radon measurement from Radonova it is straightforward to check which limit value applies to your country.

Radonova launches Polish division, reinforcing European expansion strategy

By News No Comments

Radonova Laboratories continues to expand with the announcment of a new division in Poland. Based on its strategy of appointing local specialists and partners to manage specific territories, Radonova continues to remain at the forefront of increasing awareness of the health risks associated with radon exposure, while also providing reliable, accredited measurement services.

As in many other European countries, Polish regulations have recently been amended due to the implementation of the BSS Directive. Consequently, there is increased dialogue on the dangers of radon exposure which is leading to a greater demand for radon measurements. In response to this, Radonova has spread its operations to Poland to provide industry leading technology and reliable radon measurement techniques and procedures. Across Europe, the company endeavours to ensure that the general public fully understands the implications of radon levels in their homes and workplaces.

The new division will be headed up by Zuzanna Podgórska – an experienced specialist in radon dosimetry who is well versed on local conditions and requirements.

“Changing the law, in my opinion, is the first step to raising awareness of the health risks that direct exposure to radon can cause. However, we have a long way to go before measurements become routine. It will be my role to broaden awareness in Poland, and make radon less of a niche field”, comments Zuzanna Podgórska.

“The crucial point is to provide efficient processes, service and quality. That’s why it is very important to choose a service provider who is ISO accreditated, meaning the validity of the radon data obtained from devices is recognized internationally as they are rigorously tested on a regular basis by independent third parties. It is the only way to ensure people are 100% confident that their measurements are valid and conducted in a laboratory that maintains exacting standards”, concludes Zuzanna Podgórska.

Radonova Laboratories CEO Karl Nilsson said: “By working with Zuzanna, we continue to expand our global presence at a time when the demand for reliable radon measurements increases. Zuzanna is a market specialist who brings a vast amount of experience to the table, her expertise will provide us with a strong presence in Poland. Ultimately, we want to raise awareness of the availability of our radon measurement technologies so that the dangers of radon exposure can be mitigated.”

Zuzanna Podgórska has worked as a specialist in the Central Laboratory for Radiological Protection since 2013. She has a master’s degree from Warsaw University of Technology, where she studied passive radon detectors. Her PhD studies were in the Nuclear Physics department working on geological radon mapping. She is involved in teaching and the popularization of science and has wide experience in the field of radiation protection. She is a qualified Radiation Protection Inspector.

What is radon?

Radon is a radioactive gas that leaks from the ground and in some cases comes from building materials. Depending on the ground beneath the house and the type of building construction, harmful high concentrations of radon can occur. Radon is a health risk that, after smoking, is the most common cause of lung cancer. According to the World Health Organization (WHO), 3% – 14% of all lung cancer cases are caused by radon depending on where you live. WHO recommends a limit value for radon content of 100 Bq / m3. Globally, an estimated 230,000 people are affected each year by lung cancer as a result of long-term exposure to radon.

Take Action on Radon and Radonova Collaborate on 100 Radon Test Kit Challenge

By Home, News No Comments

Radonova, the global leader in radon measurement, is proudly partnering with Take Action on Radon to supply Radtrak² radon gas detectors for the 100 Radon Test Kit Challenge.

What is the 100 Radon Test Kit Challenge?

The objective of the campaign is to gather more information about radon concentrations across Canada to increase knowledge and better understand concentration levels. The challenge targets municipalities where radon testing has thus far been limited, but where there is a potential for homes to have elevated radon levels. With the support of Health Canada, the project has already met it’s 2019 goal of singing up 15 communities. The program provides 100 test kits to each participating municipality, to be distributed to citizens for free or for a nominal fee. Each community needs to have a Community Liaison to take on this project to provide local support. Sign up here if you’re interested in becoming a community champion and joining the challenge for 2019-2020 fall and winter season.

Developing awareness about radon

“Many Canadians still don’t know that radon is the leading cause of lung cancer in non-smokers,” says Pam Warkentin, Executive Director of the Canadian Association of Radon Scientists and Technologists (CARST), and Project Manager for Take Action on Radon. “Reducing radon exposure saves lives, and the 100 Test Kit Challenge is a great way for a community to come together and address this risk.”

Radon is a colourless, odourless, radioactive gas created by the natural decay of uranium in the soil. A measurable amount of radon is found in every building, but exposure to high amounts over a long period of time presents a risk of lung cancer. Radon is the primary cause of lung cancer in non-smokers – Health Canada estimates that about 16% of lung cancer deaths are related to exposure to radon in the home. However, all homes can be tested for radon and radon levels can be reduced if they are found to be high.

Long term testing

Radtrak² is Radonova’s long-term radon gas detector which measures homes and workplaces for radon gas over a sustained period. As radon levels fluctuate from day to day, the long term test method captures radon concentrations over time to provide a better, more accurate and representative average radon gas level. Long term radon testing is also recommended by Health Canada.

Bill Rounds, President of Radonova, said: “The 100 Test Kit Challenge is an excellent example of a project that engages communities to participate and encourage radon testing, and raise much needed public awareness of the dangers of radon exposure in those areas of Canada where testing has been limited. Do not underestimate radon, it is a global health problem that is estimated to cause 230,000 cases of lung cancer each year¹. Living with high levels of radon is an unnecessary health risk. Elevated radon levels in the home can easily be reduced, but first you have to test.”

Who is Take Action on Radon?

Take Action on Radon is a national initiative which brings together radon stakeholders and raises awareness of radon across Canada. The current advisory team is made up of the Canadian Association of Radon Scientists and Technologists (CARST), CAREX Canada, and the Canadian Cancer Society. The success of this initiative hinges on the participation and dedication of hundreds of radon stakeholders coast to coast – from radon professionals and community champions to radon researchers, public health officials, and programs at the municipal, provincial, and federal levels.

Radonova is the laboratory of choice for numerous government radon surveys, as well as other public and private sector large scale measurement contracts around the world. A truly global laboratory, Radonova is active in over 50 countries and has performed millions of measurements.

New calculator simplifies radon measurement in the workplace

By Home, Workplace No Comments

To coincide with the start of the radon measurement season, Radonova has launched a web application that makes it easier to calculate how many radon detectors are required to measure radon in the workplace.

Due to national radiation protection laws which were introduced across Europe in 2018, there is now a legal requirement to measure radon levels in workplaces. The laws are based on the EU Directive 2013/59/Euratom which lays down basic safety standards for protection against the dangers arising from exposure to radiation. Therefore, employers are now responsible for controlling radon levels in workplaces, and if necessary, taking measures to lower them.

Inspired by home calculator

To meet the demand for workplace measurements, Radonova has developed a user-friendly online solution that quickly calculates how many radon detectors are needed to make a correct measurement.

”The first web application we developed calculated how many radon detectors were needed to measure radon in apartment buildings. It was a huge success which saved time and simplified the process for us and our customers. Therefore, it was logical to develop and offer a similar solution for measuring workplace environments, ”comments Karl Nilsson, CEO of Radonova Laboratories.

Workplace quality standards for radon measurement

Measurement quality standards and protocols are in place to determine how many radon detectors should be used and where they should be located. It is important to be aware that these standards vary from country to country. However, many standards and protocols are currently being reviewed as a result of the EU directive. Pending completion of various national audits, Radonova has chosen to base its calculator on the quality standards defined by the International Radon Measurement Association (IRMA). It is an established and respected standard and ensures that measurement methodologies deployed by Radonova meet both current and future international guidelines.

Get it right from the outset

Radonova’s technical director Tryggve Rönnqvist has actively participated in the development of IRMA’s standards and procedures. As Radonova is a global organisation, it has insight into the different protocols that are deployed across the world:

”Our experience is that customers don´t want to go back and forth, but would rather all appropriate measurements are carried out at the same time. Therefore, our advice is to make sure you use the correct number of radon detectors to detect problems to ensure you get the right insight if elevated values are detected. Given that we now have statistics which show that 20 percent of Swedish workplaces have elevated annual radon values, it´s even more important to follow a standard that provides the most accurate radon measurement. If you follow IRMA’s protocols, you are guaranteed to meet national requirements, regardless of country. This is why we have chosen to develop the calculator based on IRMA’s guidelines.”

The new calculator is available as a web application on Radonova’s web site.

Radon detector or digital radon sensor – which one to choose?

By Home No Comments

The market offers a variety of different radon detectors and digital radon sensors. As an individual, it can be difficult to know which one is the most appropriate for measuring radon in a house. To make things easier, we have put together a guide to better facilitate the choice of either a radon detector or digital radon sensor.

In short, it really depends on what you’re trying to achieve and measure. However, it is important to first understand how dangerous radon can be.

How can radon pose a health risk?

Radon is a radioactive gas that leaks from the ground and in some cases comes from building materials. Depending on the ground beneath the house and the type of building construction, harmful high concentrations of radon can exist.

Radon is the most common cause of lung cancer in humans after smoking. As with smoking, it is the long-term effect that can lead to cancer, the risk increases if you are exposed to high levels of radon for several years. However, staying in an indoor environment with an elevated radon content for a short time is not dangerous. To truly understand the risks in your own home, it is important to take a radon measurement over a prolonged period. This avoids getting a misleading value; radon content can vary enormously over 24 hours and can also be affected by weather conditions.

Due to the health risks and the importance of reliable radon measurements, radiation safety authorities around the world recommend that an annual average level of radon is measured. By defining an annual average value, you get the most accurate assessment of radon levels and possible health risks. The recommended maximum levels ​​found in different countries are also expressed in annual averages.

When should I use radon detectors?

If you have never conducted a radon measurement in your home and want to know what risk you may be exposed to, radon detectors are a better option than digital radon sensors. Detectors come with easy to follow instructions and should be placed in several rooms around the home. After 2-3 months, you then send the radon detectors to a laboratory for analysis.

Some of the advantages of using radon detectors:

– You get the radon content of your house expressed in an annual average that best reflects potential health risks.

– To meet national requirements place several radon detectors around the house. It is an inexpensive, robust, easy and proven method for assessing radon exposure risk.

– By using an accredited laboratory, you will receive an accurate and reliable radon content level analysis.

– Some countries offer grants to asses radon related issues. In these cases the radon content measurement is only approved if it is expressed in an annual average.

However, in order to obtain an annual average value, you do not need to conduct a radon analysis across the whole year. It usually takes 2-3 months depending on which country you measure in and what rules need to be abided by. If you choose an accredited measuring laboratory you will receive accurate and easy to follow instructions to enable you to correctly choose the right number of radon detectors for your property.

When measuring with a radon detector, it is important to understand that you cannot directly (on site) see what radon levels you have in the house. It is only the measuring laboratory that can analyze the detector – subsequently you then receive a measurement expressed in an annual average which highlights the radon level in your house.

When should I use a digital radon sensor?

Digital radon sensors are primarily used to measure the effect of a radon measure i.e. when you are proactively looking to lower radon levels. Why? Radon sensors allow the user to see how radon levels vary from hour to hour. This can be really useful if, for example, a radon suction has been installed to lower the radon content in a house.

In principle, you can also measure the annual mean with a digital radon sensor, but industry wide this is not recommended. Certainly, there are radon sensors that express the average radon content over a longer period of time. However, there are no digital radon detectors for individuals that are accredited or approved for radon measurement. Using digital radon sensors to measure the annual average is also significantly more expensive than using radon detectors because measuring radon content in one room is usually insufficient.

In most circumstances, in order to obtain a correct value, radon levels are measured in several rooms. This means that you need a number of radon sensors, which in turn can entail large costs – especially if you compare the cost of measuring an annual average with radon detectors.

In conclusion, radon detectors are the most appropriate tool for measuring the risk of radon exposure in houses.

Radon detector or digital radon sensor – which one to choose?

Canon Business Center Conducts Reliable and Effective Radon Measurement in the Workplace

By Measurement, Workplace No Comments

In order to comply with the EU’s new Radiation Protection Directive, a new Radiation Protection Act came into force in 2018. This means that for the first time, the issue of exposure and measurement of radon in both workplaces and homes is included in different European countries Radiation Protection Acts.

We met Canon’s sales manager Mats Sonesson at their Uppsala office in Sweden. Here, Mats tells us what they did to comply with the new law to ensure employees were working in a radon-safe environment.

How did you approach the issue of carrying out radon measurement in your office?
We wanted to know that the office we rent is okay and that our employees are not exposed to radon levels which are above national guidelines. As an employer, we are legally responsible to ensure our employees are not exposed to any health risks in the workplace. Understanding and controlling radon levels is a key element of that.

What was your experience of conducting an accredited radon measurement?
It was surprisingly easy. The first few days our employees wondered what the radon detectors were for, but after that they just blended into the office to the extent that we almost forgot to send them back for analysis! Registering information on Radonova’s website was straightforward and we received clear instructions on where the detectors should be placed. We fixed the detectors with zip-ties to make sure they weren’t damaged when our office was cleaned.

Have you been able to use the radon measurement you conducted in terms of your wider environmental responsibilities?
Yes, we are sending the report from the radon survey to our central office as it is something that illustrates how we are reducing our environmental impact and meeting environmental legal requirements in line with ISO 14001.

Why did you choose Radonova as your supplier?
As we are accredited according to ISO 14001, it was sensible to order the radon measurement from Radonova as the company is accredited according to ISO 17025, 14001 and 9001. Radonova’s website assures quality at a cost-effective price and in general the site is easy to navigate and order from.

Finally, do you have any advice to employers who have not yet measured radon in their workplace?
Considering how easy it is, and the fact that the law now requires measurement, the question is really why shouldn’t you do it? The measurement process is so straightforward. If the measurement would have indicated that a workplace has radon levels which are above legal levels, a significant health risk would have been identified. In that respect, it is comforting to be aware that any radon issue is being addressed and managed. In our case, the measured radon content was below the reference level.
