What is radon?

Radon is a naturally occurring radioactive gas that can be found in high concentrations indoors, such as in homes and workplaces. The gas is produced from the natural radioactive decay of uranium and can therefore be present in all types of rocks and soils. Radon can also be found in certain building materials, such as concrete and brick. Radon levels vary geographically. For example, high radon levels are typically found in Scandinavia and Austria, while countries like Australia have much lower levels. However, it is important to remember that radon levels can still be high in homes or offices built over sedimentary soils if ventilation is poor.

Why should radon be measured continuously?

Radon is one of the leading causes of lung cancer

Radon is estimated to contribute 3% to 14% of all lung cancer cases in a country affected by radon. The exact proportion depends on factors such as the national average radon level and the smoking prevalence within the population. With long-term average radon concentration, the risk of lung cancer increases by about 16% per 100 Bq/m3.

Radon levels in buildings vary from 10 Bq/m3 to 10,000 Bq/m3

In buildings such as homes, schools, and offices, radon levels can vary significantly, ranging from as low as 10 Bq/m3 to more than 10,000 Bq/m3. Due to radon's properties, occupants of these buildings can unknowingly be exposed to very high radon levels.

Radon levels vary from hour to hour

Radon levels vary greatly between adjacent buildings and even within a building from day to day and hour to hour. Because of these variations, it is recommended to measure the average indoor radon concentration continuously.

There are many ways to reduce radon levels in buildings

Some common ways to lower radon levels in existing buildings are:

  • Improving the building’s ventilation.
  • Preventing radon from passing from the basement to living areas.
  • Sealing walls and floors.

Radon sensor

Our radon sensor is well suited for controlling ventilation due to frequent data collection. It can also be used to generate long-term averages that can serve as a basis for decisions on radon mitigation measures, as you receive all data directly into your system.
