A typical radon test kit Fluctuation of ambient air radon concentration over one week, measured in a laboratory. The first step in mitigation is testing. No level of radiation is considered completely safe, but as it cannot be eliminated, governments around the world have set various action levels to provide guidance on when radon concentrations should be reduced.
To achieve these aims, WHO has formed a network of key partner agencies from some 40 Member States. This network is the basis for the WHO International Radon Project which was launched in 2005. Working groups will collect and analyse information on radon risk, radon policies, radon mitigation and prevention as well as risk communication.
ASTM E-2121 is a standard for reducing radon in homes as far as practicable below 4 picocuries per liter (pCi/L) in indoor air. [111] [112] In the US, approximately 14 states have a state radon programs which train and license radon mitigation contractors and radon measurement professionals.
Radon is measured in picocuries per liter of air (pCi/L) or becquerel per cubic meter (Bq m-3). Both are measurements of radioactivity. The World Health Organization (WHO) sets the ideal indoor radon levels at 100 Bq/m-3. [97] In the United States, it is recommend to fix homes with radon levels at or above 4 pCi/L.
In 1987 he started his own company providing basement waterproofing and radon mitigation services, calling it Connecticut Basement Systems. [9] Janesky invented and developed a line of waterproofing products of which he was the exclusive installer. He acquired patents on his waterproofing products and currently holds 31 patents.

It is possible to test for radon in buildings, and to use techniques such as sub-slab depressurization for mitigation. [ 9 ] [ 10 ] Epidemiological studies have shown a clear association between breathing high concentrations of radon and incidence of lung cancer . [ 11 ]
