Lifetime cancer risk increase due to consumption of some foods from a High Background Radiation Area

Abstract

Activity concentration (AC) in foods produced and commonly consumed in a High Background Radiation Area (HBRA) was analyzed. The AC were obtained by spectrophotometry and by the radiochemical separation method. The AC were up to 104 times higher than the AC for both UNSCEAR suggested values and non-HBRA. It was noted that the lifetime cancer risk was increased in 4 decimal places, taking the risk from the "statistically negligible range" (<10-6) to "middle range" (between 10-4 and 10-6).

Keywords: Activity concentration; Fish; Naturally occurring radionuclides; Uranium mine; Vegetables.
