Jan 5, 2015 · For that reason, the term “radon” identifies mainly the 222 Rn and this is the convention followed thereafter. Radon ( 222 Rn) is released primarily from soil and approximately 10% of it is released into the atmosphere ( 3, 4 ). 218 Po, 214 Pb, and 214 Bi are radon’s most significant progeny in terms of radiation dose. Since the 1960s, studies on underground miners have consistently demonstrated an increased risk of lung cancer caused by radon and its progeny (15). Based on this evidence, IARC classified radon as a human carcinogen in 1988 (46). Since then, several reviews on radon-related risk among miners have been published (1,4,21,28).A change in the number of chromosomes can cause problems with growth, development, and function of the body's systems.
