The main isotope of radon is radioactive with a half-life of 3.9 days, and the nuclear decay of radon is known to have an ionizing effect on air. Many publications have reported increased radon concentration in the vicinity of some active tectonic faults a few weeks prior to strong seismic events. [27]
Radon is potentially useful as an earthquake predictor because it is radioactive and thus easily detected, [f] and its short half-life (3.8 days) makes radon levels sensitive to short-term fluctuations. A 2009 compilation [59] listed 125 reports of changes in radon emissions prior to 86 earthquakes since 1966. The International Commission on ...
Radon, a byproduct of naturally decaying uranium, is estimated to cause thousands of deaths each year nationwide. Here's how to protect yourself.
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]
The global average internal dose from radionuclides other than radon and its decay products is 0.29 mSv/a, of which 0.17 mSv/a comes from 40 K, 0.12 mSv/a comes from the uranium and thorium series, and 12 μSv/a comes from 14 C. [2]
