ASSESSMENT OF RADON-222 IN SOME SELECTED WATER SOURCES ABSTRACT Radon is one of the sources of nuclear contamination in water and the la

A common source is uranium-containing minerals in the ground, and therefore it accumulates in subterranean areas such as basements. Radon can also occur in some ground water like spring waters and hot springs. Epidemiological studies have shown a clear link between breathing high concentrations of radon and incidence of lung cancer. radon sources in the US include i) uraniferous metamorphic rocks and granites, especially fault shear zones in these rocks in the Sierra Nevada, Rocky, and Appalachian mountain ranges; 2020-08-16 · Radon (more properly known as radon-222) comes from uranium which occurs naturally in many different types of rocks and soils.

Radon-222 is a member of the radioactive decay chain of uranium-238. Radon-220 is formed in the decay chain of thorium-232.

Radon, chemical element, a heavy radioactive gas of Group 18 (noble gases) of the periodic table, generated by the radioactive decay of radium. It is a colorless gas, 7.5 times heavier than air and more than 100 times heavier than hydrogen. Learn more about radon in this article.

Radon is an element which is dissolved and can sometimes be found in the water wells. You cannot smell, see, or taste radon. However, you can drink it, especially when your main water source is the water well.

Radiation Protection (ICRP); Rn-222 isotope is a major source of internal radiation in human life. (6). The effect of radon on human health through breathing is

Le radon 222 peut être inhalé (poumons) ou ingéré s’il est dissous dans certaines eaux minérales (activité de 10 Bq/L). Radon-222 is one of the elements in the long radioactive decay chain from uranium-238, and the less common isotope radon-220 is part of the decay series from thorium-232. The elements above radon in the chain are relatively long-lived and of less concern for radiation exposure, but radon and the elements immediately following it in the chain are short-lived and therefore more hazardous. Radon-222 is a member of the radioactive decay chain of uranium-238.
