Because they are radioactive, radon and radon progeny emit alpha particles, a high-energy radiation that damages DNA in human cells and causes lung cancer. When radon is inhaled, particles become lodged in the lungs where they continue to emit alpha particles. ...
Radon gas contains radioactive particles which get trapped in your lungs every time you take a breath. As these particles break down, they release bursts of radiation that damage or destroy lung tissue and cause lung cancer, and long-term exposure may even cause death. Do you have any of ...
When a mixture of trace amounts of radon-222 and fluorine gas are heated to approximately 400°C, a nonvolatile fluoride is formed. The intense γ-radiation of millicurie and curie amounts of radon provides the activation, allowing radon in such quantities to react spontaneously with gaseous ...
Region Lombardia has carried out a radon gas monitoring survey on its territory to localize radon prone areas as by law 241/00 enacted. To plan the survey, the Lombardia territory has been divided into two different types according to the morphology as well as the presence of a substratum of...
Radon gas is the main natural source of exposure of the population to ionizing rays. Because of its impact on the health, this radioactive gas has become a great concern worldwide. In this study, radon concentrations in the air of some dwellings in Yopougon, one of the commune with the ...
Radiation Protection Dosimetry 46: 149–170.) While the major removal of radon gas from air is by radioactive decay, the chemically radioactive decay products (formerly called radon daughters) may additionally be removed by processes such as wash-out and plating-out on surfaces. In air inside ...

Since the soils have generally about 103–104 times gas concentrations than in the atmosphere, there is always a concentration gradient present which is maintained by the continuous decay of radioactive elements. Commonly used earth-based building materials, like bricks, sand, cement, etc., also ...
