CAUSATION/RISK FACTORS
Cells May Be More Sensitive to Radon Damage. A study published April 27 in the Proceedings of the National Academy of Sciences indicates that cells may be more sensitive to radiation from radon than previously believed, The researchers from Columbia University in New York found that high-energy particles do not have to score a direct hit on the nucleus of a cell in order to cause damage, but can induce genetic changes even if they strike the fluid surrounding the nucleus. Exposure to radon gas is thought to cause about 21,000 lung cancer deaths in the United States each year; however, the researchers were unsure as to how their findings would affect these statistics.
