摘要

利用伽马和阿尔法光谱仪测定了淡江-丘海（TG）、氏泥（TN）和奈（DN）泻湖的三个沉积物岩芯中的放射性同位素 226Ra、210Pb、232Th 和 40K，并计算了辐射风险指数。210Pb、40K、232Th 和 226Ra 的放射性浓度分别为 55.46 Bq/kg、675.78 Bq/kg、67.22 Bq/kg 和 34.15 Bq/kg。Raeq、ADR、AEDE、Iγr、AUI、Hex和AGDE指数分别为182.31 Bq/kg、84.46 nGy/h、0.10 mSV/y、1.35、1、18、0.49和598.71 µSV/y；40K、232Th、AEDE、ADR、Iγr和AGDE值均大于全球平均值和UNSCEAR值。放射性和辐射风险指数的下降顺序为 DN > TN > TG。

Assessment of radioactivity and radiological risk indices in the sediments of the Tam Giang-Cau Hai, Thi Nai, and Nai lagoons in the Center of Vietnam

Using gamma and alpha spectrometers, the radioactive isotopes 226Ra, 210Pb, 232Th, and 40K were determined in three sediment cores from the Tam Giang-Cau Hai (TG), Thi Nai (TN), and Nai (DN) lagoons, and radiation risk indices were computed. The radioactivity concentrations of 210Pb, 40K, 232Th, and 226Ra were 55.46 Bq/kg, 675.78 Bq/kg, 67.22 Bq/kg, and 34.15 Bq/kg, respectively. The Raeq, ADR, AEDE, Iγr, AUI, Hex, and AGDE indices were 182.31 Bq/kg, 84.46 nGy/h, 0.10 mSV/y, 1.35, 1, 18, 0.49, and 598.71 µSV/y, respectively; the values of 40K, 232Th, AEDE, ADR, Iγr, and AGDE were greater than the global average and UNSCEAR values. The radioactivity and radiation risk indices decreased in the order DN > TN > TG.
