The threat of lung cancer rises by 16% per 100 Bq/m3 boost in long period of time average radon concentration. The dose-response relationship is linear-- for example, the threat of lung cancer cells enhances proportionally with increasing radon direct exposure. Radon is one of the most essential reason for lung cancer after smoking cigarettes. It is approximated that radon creates between 3-- 14% of all lung cancers cells in a nation, depending upon the average radon degree and also the smoking occurrence in a nation. Radon gets away conveniently from the ground into the air, where it decays and also creates additional contaminated particles.
