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).

由于食用来自高背景辐射区域的某些食物，终生患癌症风险增加

分析了在高背景辐射区 (HBRA) 生产和通常消费的食物中的活度浓度 (AC)。AC通过分光光度法和放射化学分离法获得。对于 UNSCEAR 建议值和非 HBRA，AC 比 AC 高10 ^4倍。值得注意的是，终生癌症风险增加了小数点后 4 位，风险从“统计上可忽略的范围”（<10 ^-6）到“中间范围”（在 10 ^-4和 10 ^-6之间）。
