About #radon gas: Although #radon is a natural radioactive gas, elevated #radon levels indoors are not natural but a by-product of building practices. #radon levels may change daily, and #radon gas accumulation occurs indoors in all type of buildings.
#radon as a health risk: It has been scientifically proved throughout several scientific studies that exposure to #radon gas is the second leading cause of lung cancer (Darby S. et al, Scand j Work Environ Health 2006;32 (1):1-84; Darby et al, BMJ, doi:10.1136/bmj.38308.477650.63 (published 21 December 2004); Lubin at al, Int. J. Cancer: 109, 132–137 (2004); Lubin et al, Journal of Toxicology and Environmental Health, Part A Vol. 69, Iss. 7-8, 2006). #radon decay products attach to the respiratory system and may cause damage to our DNA.
EURATOM BSS: The new Directive establishes a reference level of 300 Bq m-3. The Directive mandates member states to monitor #radon levels in dwellings, work places and public areas. A detailed list of actions is included on the document and all member states have to set up a national #radon action plan.
