Radon levels fluctuate naturally, due to factors like transient weather conditions, so an initial test might not be an accurate assessment of a home's average radon level. Radon levels are at a maximum during the coolest part of the day when pressure differentials are greatest. [ 77 ]

In a working mine, the radon level can be controlled by ventilation, sealing off old workings and controlling the water in the mine. The level in a mine can go up when a mine is abandoned; it can reach a level which can cause the skin to become red (a mild radiation burn). The radon levels in some of the mines can reach 400 to 700 kBq m −3. [17]
According to the World Health Organization, radon is a naturally-occurring radioactive gas with no smell, color or taste. Radon escapes from the ground into the air, where it produces further ...
Under this modeling, the best policy is obviously to reduce the radon levels of all homes where the radon level is above average, because this leads to a significant decrease of radon exposure on a significant fraction of the population; but this effect is predicted in the 0–200 Bq/m 3 range, where the linear model has its maximum uncertainty ...
Levels of radioactivity in the Trinity glass from two different samples as measured by gamma spectroscopy on lumps of the glass. One dramatic source of man-made radioactivity is a nuclear weapons test. The glassy trinitite created by the first atom bomb contains radioisotopes formed by neutron activation and nuclear fission. In addition some ...

Radon-222 (222 Rn, Rn-222, historically radium emanation or radon) is the most stable isotope of radon, with a half-life of approximately 3.8 days. It is transient in the decay chain of primordial uranium-238 and is the immediate decay product of radium-226 .
