Abstract

238U, 234U and 210Po activity concentration was determined in 70 samples of red and white wine coming from 16 Italian regions. The radionuclides were determined by alpha spectrometry after separation. The results show that the mean concentrations of 238U, 234U and 210Po were 3.63 x 10(-3)+/-2.19 x 10(-3), 4.41 x 10(-3)+/-3.10 x 10(-3) and 6.85 x 10(-2)+/-3.79 x 10(-2) Bq L(-1) for red wine and 5.08 x 10(-3)+/-4.20 x 10(-3), 5.59 x 10(-3)+/-8.49 x 10(-3) and 3.92 x 10(-2)+/-2.63 x 10(-2) Bq L(-1) for white wine, respectively. The effective radiation dose due to the uranium and polonium ingestions by wine (0.5l per day) ranges from 2.68 x 10(-4) to 4.91 x 10(-2) mSv year(-1).

摘要

测定了来自意大利 16 个地区的 70 份红葡萄酒和白葡萄酒中 238U、234U 和 210Po 的活度浓度。这些放射性核素通过分离后用α谱法进行测定。结果表明，红葡萄酒中 238U、234U 和 210Po 的平均浓度分别为 3.63 x 10(-3)+/-2.19 x 10(-3)、4.41 x 10(-3)+/-3.10 x 10(-3)和 6.85 x 10(-2)+/-3.79 x 10(-2) Bq/L，白葡萄酒中 238U、234U 和 210Po 的平均浓度分别为 5.08 x 10(-3)+/-4.20 x 10(-3)、5.59 x 10(-3)+/-8.49 x 10(-3)和 3.92 x 10(-2)+/-2.63 x 10(-2) Bq/L。每天饮用 0.5 升葡萄酒时，铀和钋通过摄入产生的有效辐射剂量范围为 2.68 x 10(-4)至 4.91 x 10(-2) mSv/年。
