Radonova launches new radon dosimetry product  

By January 27, 2021News, Measurement

Radonova has launched a new radon dosimetry product. To understand the rationale for the product launch we’ve asked Radonova’s CEO, Karl Nilsson, a few questions… 

Why did you choose to develop the new product?

We see an increased requirement for a complete radon dosimetry solution. Put simply, the new service measures individual employee exposure to radon. Historically, mines and other underground workplaces have deployed radon dosimetry solutions. However, times change and in terms of the EU’s new radiation protection directive and national radiation protection laws, the need to conduct radon dosimetry practices above ground has increased. Employees who work in rooms with elevated radon levels will be safer if a radon dosimetry procedure is conducted.

What makes Radonova’s radon dosimetry unique?

Our radon dosimetry product is accredited according to ISO 17025 and offers a simple solution where the customer can use it without being an expert on radon related issues.

How does the measurement work?

The customer places an order and we deliver radon dosimeters to individual workers. They wear them for three months (during working hours) and then send the dosimeters back to us. Within two weeks, each employee receives a report indicating their exposure to radon. A comparison is made to the national limit value for each country. At the start of every three-month period, employees receive a new dosimeter. The next report shows both the accumulated exposure and the exposure for the current measurement period. After a year, reports are sent out which illustrate annual radon exposure. This is the measurement which should normally be reported to the national radiation protection authority.

Where can I find more information?

The easiest way is to go to our website There you can find more detail and get in touch with one of our radon experts who can provide advice. Radon is a radioactive gas that is formed naturally when the uranium-238 isotope decomposes. The radon gas decomposes and turns into radon daughters. Radon daughters are radioactive metal atoms that get stuck in our lungs when inhaled. The radiation emitted from radon daughters is proven to cause damage to the cells in our airways and lungs. In the worst case scenario, it can lead to cancer. According to the World Health Organization 3 to 14 percent of all lung cancer cases are caused by radon.
