ATMOS: New version of the world’s lightest and most sensitive radon sniffer

By | Measurement, News | No Comments

Radonova Laboratories is launching a completely new version of the radon sniffer ATMOS. The new version weighs 4.5 kg , has a new design, several new features and enhanced software functionality. The new ATMOS is designed to enable even faster and more efficient radon measurements in the field. The latest version of ATMOS is now commercially available.
The instrument has been developed to meet the needs of an international market that is growing and demanding modern, user-friendly instruments for radon measurement.

Increased demand for radon measurement

The need for reliable and flexible field instruments has increased as more and more homes and workplaces show increased levels of radon.
In the case of a radon inspection, the user normally searches for the leakage of radon and therefore needs an instrument that can quickly display the correct radon content. Therefore, there is sometimes a need to measure the variation of radon every minute and in various contexts to clarify daytime variations. In this circumstance, ATMOS makes the radon consultant’s everyday life easier and more efficient.

Fast and reliable measurement reports

ATMOS is unique because it is the most sensitive and lightest instrument that can be used both in the field and in a laboratory.
– Thanks to its light compact format and general portability, ATMOS can easily be taken out for radon inspection of properties. The updated software makes it very easy to extract data and quickly create reliable measurement reports. The latest version of ATMOS enables radon consultants to conduct considerably more measurements compared to other instruments on the market in a 24 hour period, says Patrik Starck, technical physicist and Radonova’s development manager.
– Compared to previous versions, the instrument has essentially been completely redesigned. The only part that remains is the measuring chamber. That particular part is based on a proven technique and it is doubtful whether you can improve the design, continues Patrik Starck.

Growing international market

Previous versions of ATMOS have mainly been delivered and used in Sweden. With increased international demand, Radonova has scaled production at the company’s plant in Uppsala.
– It is of course gratifying when we now see clear demand outside Sweden. The new ATMOS has been launched after several years of research and development. The positive response from the market is an acknowledgment that more and more people and businesses are seeing the benefits of the instrument, comments Karl Nilsson, CEO, Radonova Laboratories.

New ATMOS specifications:

  • Light and compact, simplifying field work
  • Weight: 4.5 kg Size: 500 x 385 x 220 mm (W x H x D)
  • New software enables fast and secure measurement reports
  • The pulsation chamber has high sensitivity and a fast response time
  • Chirp function – listens to how high the content is in confined spaces
  • Communication to PC via USB
  • > 10 year history for measurement data

The basic version of ATMOS costs SEK 89,450 excluding VAT.

Risks with radon

Radon is a radioactive gas that forms naturally when the substance Uran238 decomposes. Thereafter, the radon gas, in turn, decomposes into radond daughters. Radon daughters are radioactive metal atoms that get stuck in our airways during inhalation. When this disintegration occurs, radiation is emitted from the radon daughters that can damage the cells in our airways and lungs. In the worst case, they can cause cancer. According to the World Health Organization (WHO), 3-14 percent of all lung cancer cases are caused by radon depending on where you live. Therefore, WHO recommends a radon level limit of 100 Bq/m3.

ATMOS product description

ATMOS has a built-in dehumidification to ensure that the moisture content of the air does not interfere with the measurement. The dehumidifier works in saturated moisture at temperatures up to 40ºC. 40 degrees C. ATMOS also shows a table of the 10 latest measured levels per selected integration time. To each calculated radon measurement the user is presented with the associated uncertainty in measurement. The dehumidification of the air in ATMOS takes place automatically and is fully integrated in the instrument. The atmospheric pressure, temperature and humidity of the air are shown in the display and stored together with each measurement. Due to the fact that the measurement value is displayed directly at a new measurement, the user does not have to wait for the end of the measuring cycle.
ATMOS includes software for analyzing measurement data. The display is a 3.5 ? touch screen that shows the radon content in Bq/m³, the uncertainty since the start time of the measurement, integration time, measurement time, time and date. In addition, a field storage bag with detachable lid, 24VDC mains adapter and 3 meter hose with instrument adapter are included. The readout and reporting software works in Windows and is included with the instrument. The software is used to read out stored measurement data to evaluate time variations and energy spectrum. In addition, the software is compatible with older versions of Windows.
The instrument measures the alpha decay of radon and its daughters and is completely insensitive to gamma radiation. The alpha energies of the different isotopes are detected and the radon concentration is displayed in a touch display on the instrument. The user selects the desired integration time, the longer the time the more accurate the measurement. The measurement energy spectrum is stored every 10 minutes during the measurement and always gives the user the opportunity to quality-assure the measurement data. A measurement value is displayed directly at a new measurement and the user does not have to wait.

How many radon detectors are needed to measure a workplace?

By | Uncategorized | No Comments

Since the EU’s new radiation protection directive (2013/59/Euratom) came into force in 2018, it is mandatory that employers should be aware of radon levels in the workplace. The new directive has entailed new national laws in member states, which has resulted in an increasing number of workplaces measuring radon levels. However, at the same time, there is a lack of knowledge about how a safe and reliable radon measurement should be conducted.

As the world’s leading radon laboratory, Radonova Laboratories has produced a “how to guide” that can help employers carry out radon measurements correctly.

First get an overview – long term measurement by an accredited laboratory

If you have never measured radon before, you should start first with a preliminary measurement by an accredited laboratory. These measurements should be carried out over a three-month period in order to obtain an annual average of the radon level. Note, this initial measurement must be performed during specific measurement seasons in some countries.

The main cost is not radon detectors – make sure you get it right from the start

When ordering a radon measurement, a common question is how many radon doses are needed. Unfortunately, many countries do not have an official methodology detailing how a measurement at a workplace should be carried out. And if there is, they are usually very difficult to interpret for most employers. Therefore, it can be hard to estimate the number of radon doses required. For this reason, we recommend that employers who measure radon levels use the international methodology recommended by The International Radon Measurement Association (IRMA). Yes, it will result in more measuring points than is suggested by a national organisation, but by following IRMA guidelines you do not risk missing certain areas of the workplace, which can result in time-consuming remeasuring.

The main cost of workplace radon measurement is in the deployment and collection of detectors and the investment in radon consultants if remeasurements are required. In the event of elevated radon levels, the commissioned radon consultant will be in a position to work more efficiently if more points have been measured at the outset. So, by following IRMA guidelines, you will have access to relevant documentation which enables you to conduct measurements which are appropriate for your business.

Rules for calculating the number of radon detectors.

The guidelines in IRMA’s method description for calculating the number of radon doses required are straightforward. By following them, you will also meet national criteria for measuring radon in workplaces.

Here’s how to calculate the number of radon detectors based on IRMA’s guidelines:

• Radon detectors should be placed in rooms where employees spend more than 4 hours per day and in basements where staff stay more than 50 hours a year

• For larger rooms and premises in the ground floor or basement, a radon detector per 150 m² should be placed

• For larger rooms and premises on other floors, a radon detector per 250 m² should be placed

• Use at least two radon detectors per building and floor

• Always measure in rooms where you and your colleagues spend the most time

If you have additional questions about the required number of radon doses and how to conduct a radon measurement, why not contact Radonova’s specialists.

Radiation measurement: from timber to wild boar

By | News | No Comments

Radonova’s story begins in 1986 when a group of researchers at Uppsala University in Sweden were commissioned to measure the radioactive fallout from the Chernobyl accident in Sweden and beyond. Today the company focuses primarily on radon measurement, a field in which we are the global leader.

Each year, though, Radonova also carries out a large number of radiation measurements on everything from wild game meat to timber. Our customers are authorities, private individuals and companies.

“Although our core business these days is radon measurement in homes and other premises, we regularly carry out other forms of radiation analyses. We have so far conducted around half a million analyses, in addition to radon measurement,” comments Oscar Wännerud, a laboratory manager at Radonova Laboratories.

Participated in several wildlife projects

Over the years Radonova has collaborated on projects with a number of authorities and organisations. Radonova also performs caesium analyses for customers in Europe and Asia.

“A lot of our analyses have involved reindeer meat and have been commissioned by the Swedish Board of Agriculture and more recently Sametinget (the Sami Parliament). We have also carried out a large number of measurements on wild boar meat and have participated in the Swedish Radiation Safety Authority’s project offering free measurement of caesium-137 in meat from wild boar,” continues Oscar.

Radiation levels can be high in wild boar because the animals root for food and consume berries, mushrooms and roots or other foodstuffs that have lain in the soil for a long time. The wild boar also ingests a lot of soil that may also contain caesium-137.

Easy to carry out radiation measurement

Like radon measurement, radiation measurement of foodstuffs and other items is often relatively simple. “Generally speaking, it is easy to order and submit a sample of foodstuff for radiation measurement. Over the years we have received a lot of foodstuffs, including wild game meat, mushrooms, berries and fish, as well as some more unusual items, such as a tree stump, a cot, lynx testicles, vodka, snus and cigarettes. These are items you wouldn’t normally associate with radioactive radiation. When it comes to foodstuffs and items that are in close proximity to people for a prolonged period, it is, of course, prudent to conduct a measurement. Especially when you consider that exposure to radiation can have serious consequences and increase the risk of cancer,” concludes Oscar Wännerud.

British Columbia Lung Association to Provide Radonova’s Test Kits for Home, Workplace and School Radon Monitoring

By | Measurement, News | No Comments

Through its partnership with Radon Environmental, the British Columbia Lung Association (BCLA) is providing Radonova’s radon detectors to consumers to offer a fast, efficient, and accurate way to find out if your home, school or workplace has potentially hazardous indoor radon levels. The detectors supplied by the BCLA gives the public the option of choosing either a short or long-term test kit. All test kits provided are recognized by Health Canada and C-NRPP certified. This news follows on from The Lung Association – Ontario also announcing that it would be offering Radonova’s state-of-the-art radon monitors to the general public.

“The air you breathe, regardless of where you live or work, is important to your health. The BC Lung Association is committed to protecting your breathing and that’s why we are excited about being able to offer a variety of radon test kits for the public,” said Christopher Lam, President & CEO of the BC Lung Association.

The two alpha track radon detection devices the BCLA will be making available to the public are Rapidos and Radtrak². Rapidos is a short-term radon measurement test kit that captures a measurement of radon levels over a 10-30 day period. Measurement reports are available from Radonova’s laboratory within 1-2 weeks after the laboratory has received the detectors.

Both accurate and flexible, Rapidos is one of the most effective and flexible ways to measure radon in residential buildings, workplaces and schools.

Radtrak² is Radonova’s flagship long-term radon test kit and tests home’s and workplaces for radon over a sustained period, as encouraged by Health Canada. With ultra-high accuracy over a prolonged period of time, it provides a full and clear perspective on the risk of radon exposure in the tested location.

Radon is an invisible, odourless and tasteless gas that can accumulate to unnaturally high and dangerous levels in homes and workplaces. Young people and children are more vulnerable to radiation as they have higher respiratory rates than adults. However, consumer knowledge on how to detect Radon and meaningfully reduce exposure is still relatively low.

Bill Rounds, President at Radonova, said: “Our work with the various Lung Associations in Canada highlights that the general public and businesses are gradually becoming more aware of the dangers of radon. Radon is a global health problem that is estimated to cause 230,000 cases of lung cancer each year¹. A recent report by the World Health Organization states that radon should be regarded as a carcinogen on a par with tobacco smoke². The technologies we offer ensure customers are receiving a reliable, high quality measurement that will aide in helping individuals make decisions about their home’s indoor air quality. Living with high radon is truly an unnecessary health risk. Elevated radon levels in the home can easily be reduced, but you have to test to know.”

Radon Environmental President & CEO, Alan Whitehead commented: “We’re delighted to have expanded our Radon Testing Device and Service Agreement with the British Columbia Lung Association, to provide our extended range of Radonova short term (Rapidos) and long term (Radtrak²) alpha track radon detection devices. We supply many local health authorities and public testing initiatives across Canada and our partnership with the BCLA will lead to increased public awareness and radon testing in British Columbia. Radtrak² has the largest range of detection of any alpha track device and the Radonova laboratory is the only ISO17025 certified alpha track testing facility of its kind, so our clients can be confident in the lab analysis and its QA process. One of the features that our clients like the most is RadOnline, Radonova’s online customer portal. Through MyPages, customers can easily input measurement data, retrieve reports, and have an overview on every project, in real-time.”

Busy Times in the Radonova Lab – Nearly 30,000 Detectors Analyzed in One Week

By | Measurement | No Comments

May always equates to a seasonal peak for Radonova. This year, the world’s leading radon laboratory beat previous records for the number of detectors analyzed in one week. Oscar Wännerud who is responsible for Radonova’s laboratory, comments on the season high:

– In May, we enter our most intensive period when it comes to incoming deliveries of radon detectors. In many countries, the radon measurement season ends at the end of April, resulting in a peak of incoming detectors. This year we peaked in the third week of May when we analyzed a total of 29,626 detectors. It is a historical record for Radonova and another acknowledgment that we are the world leader in radon measurement and analysis.

Maintaining quality standards and rapid analysis in the face of increased digitization

– One of the biggest challenges during this part of the season is to keep the analysis time down. This was achieved even though there were huge volume pressures on the laboratory. It’s worth stating that customers should register their information via My pages. By doing so, they are guaranteed to get the shortest possible analysis time. – At our laboratory we have a committed and competent workforce with extensive experience in the radon industry, increased digitization and automation means that we are scaling-up our operations but never at the expense of quality. – As a service we are constantly evolving and questioning established routines. We believe it is always possible to improve processes to ensure smoother operations.

The significance of new legislation

Since the EU’s new Radiation Protection Directive (2013/59/Euratom) began to be applied in 2018, Europe’s employers have become responsible for controlling the radon content in workplaces.

– We have seen a clear increase in the number of companies measuring radon in the work environment. Given the health risks that elevated radon levels causes, it feels good to be part of a team that is ensuring that fewer people are exposed to high radon levels. Remember it is easy to measure radon, both for private individuals and employers. Our customer service team is always keen to speak to anyone who has questions or is uncertain about how to go about conducting a test.

Intercomparison test: Radonova receives high marks from PHE

By | Measurement, News | No Comments

Radonova Laboratories has achieved outstanding results in a preliminary comparative reference test performed by the state-owned PHE (Public Health England). The intercomparison tests were performed at five different radon levels – Radonova participated with two different types of detectors for each exposure. In all ten cases, Radonova’s results differed by less than 4% from the respective reference value.
During the reference test, radon detectors were exposed to different levels of radon. The results are then compared to the official reference values as dictated by PHE. Radonova’s detector Duotrak had a particularly small deviation where three out of five tests deviated by less than one per cent from the reference value.

Demanding test

“For several years, Radonova has regularly been involved in this type of comparative reference test. We are consistently given high marks but are still very pleased by the fact that this is probably our best result so far. It feels particularly good when we are constantly working on developing and refining our radon detectors as well as instruments and measuring methods,” said Radonova Laboratories CEO, Karl Nilsson.
“PHE’s comparative reference test is among the most demanding in the industry. It tests both low and high exposures which places particularly high demands on reliability. We are always looking to offer our customers the highest quality technology and take this as an acknowledgment that we continue to be at the forefront of the market for radon measurements,” comments Bill Rounds, President of Radonova.
The radon detectors were subjected to exposure between 137 – 2180 kBqh/m3. PHE is expected to publish the report towards the end of 2019.
