The danger of lung cancer boosts by 16% per 100 Bq/m3 increase in long time ordinary radon concentration. The dose-response connection is straight-- for example, the threat of lung cancer raises proportionally with enhancing radon direct exposure. Radon is the most essential root cause of lung cancer after smoking cigarettes. It is approximated that radon creates between 3-- 14% of all lung cancers cells in a country, depending on the typical radon degree and the cigarette smoking occurrence in a nation. Radon runs away quickly from the ground right into the air, where it decays as well as produces more radioactive fragments.
