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.
The goals of NRAP are to continue efforts set forth by FRAP to eliminate radon induced cancer that can be prevented by expanding radon testing, mitigating high levels of radon exposure, and developing radon resistant construction. [87] NRAP also aims to reduce radon risk in 5 million homes, and save 3,200 lives by 2020. [87]
Radon is a major cause of cancer; it is estimated to contribute to ~2% of all cancer related deaths in Europe. [1] Radium, like radon, is radioactive and is found in small quantities in nature and is hazardous to life if radiation exceeds 20-50 mSv/year. Radium is a decay product of uranium and thorium. [2]
An open-land test kit can test radon emissions from the land before construction begins. [13] Radon concentrations can vary daily, and accurate radon exposure estimates require long-term average radon measurements in the spaces where an individual spends a significant amount of time. [174]
A Lucas cell can be used to measure radon gas concentrations. [2] Radon itself is an inert gas.Its danger lies in the fact that it undergoes radioactive decay.The radon decay products may lodge in the lungs and bombard them with alpha and beta particles, thus increasing the risk of lung cancer.
Working level (WL) is a historical unit of concentration of radioactive decay products of radon, applied to uranium mining environment. [1] One working level refers to the concentration of short-lived decay products of radon in equilibrium with 3,700 Bq/m 3 (100 pCi/L) in air. These decay products would emit 1.3 × 10 5 MeV in complete decay. [2]
