What is radon ?

Radon is a radioactive noble gas that is naturally present in all layers of rock. It is the heaviest of all natural gases and is seven times heavier than air alone. Radon is formed from radium-226, which in turn is the decay product of uranium-238. In addition to radon, the gaseous radon issotopes thoron and actinone are also formed in this decay process.

However, these gases decompose within seconds and are not dangerous to humans. Radon-222 has a half-life of 3.8 days. However, since radon is constantly being formed from radium or uranium, which has a half-life that is several zeros higher, the problem of radon exposure in radiation protection always remains acute.

Radon-222 breaks down into the radioactive heavy metal isotopes polonium-218, bismuth-214 and lead-214 to the no longer radioactive end product lead-206. In the wild, the substance mixes with the surrounding air.

There is no danger for humans here and the radiation exposure in the air is only 1 to 30 becquerels per cubic meter. However, there is a risk in closed rooms, where radon enters the living space mainly through the basement, but also through pipes, ducts and building material containing radon and accumulates in the living air. In addition, radon can enter the house through the groundwater and unfold its effect.

Radon measurement in Switzerland

Radon Action Plan 2021-2030

Despite having a population relatively well educated regarding radon compared to many other countries in Europe, (55% of the population declares having a knowledge about radon) a lot of buildings remain to measure.

Indeed, according to the Radon Action Plan 2021 – 2030, only 6% of all buildings in Switzerland has been measured for radon to date. Among those buildings, 10% are showing radon concentrations above the reference level of 300 Bq/m3.

Radon in Switzerland is therefore an issue and lots of measurements still have to be conducted in the coming years throughout the country and regardless the location of the building on the map. Indeed, construction design and occupiers habits have a higher impact on indoor radon concentration than natural hazard itself.

When to measure radon ?

Measuring radon in Switzerland is regulated by the ordonnace on radioprotection (ORaP) of the 26th of April 2017.

The ordonance definies several cases where radon measurement hcan or have to be performed :

  • Permission procedures for new buildings and extensions (art 163): an evaluation of the radon situation must be performed to ensure that the levels of radon will remain below the reference level of 300 Bq/m3.
  • Schools and public buildings (art 164) : The canton is responsible for measuring radon. The measurement has to be performed by an approved radon measurement provider.
  • Worplaces (art 165) : workplaces exposed to radon must be measured for radon. As for achools and public buildings, radon measurements have to be conducted by an approved radon measurement provider
Consult the Ordonance on radioprotection (ORaP)

Who can meaure radon ?

According to the article 159 or the ORaP, regulated measurement framed by the ORaP must be performed by an approved  measurement provider listed by the FOPH.

As the Swiss leader in radon measurement, Radonova is working with a lot of approved measurement providers who made the choice of quality by working with us.

Note that of course it is always possible to conduct a radon measurement on goodwill without using the services of an approved measurement provider. However, the measurement will not have any legal value.
