Answer to Question #5181 Submitted to "Ask the Experts"Category: Environmental and Background Radiation — Food, Plants, Animals The following question was answered by an expert in the appropriate field: Q
I would like to know about radioactivity in salt. A
Common table salt is sodium chloride; neither sodium nor chlorine, as found in nature, is radioactive. However, salt does contain trace amounts of impurities and thus includes tiny and insignificant trace amounts of natural radioactivity (for example, uranium, radium).
There is also a low-sodium salt substitute which contains potassium chloride. All potassium contains trace amounts of the radioactive isotope potassium-40. Ron Kathren, CHP
