摘要

在越南湾沿岸的海洋沉积物、海水和海产品中测定了天然存在的放射性核素226Ra、232Th和238U的活度浓度,为今后在0-3厘米的地表水深度进行环境监测建立基线数据。铀、钍和镭的浓度是用低本底伽马谱以及238U(214Bi)、232Th(228Ac)和226Ra的活度来测定的。海水样品中226Ra、232Th和238U的平均放射性浓度分别为8.59±0.54、1.31±0.15和6.91±0.64 Bq m−3,海洋沉积物中226Ra、232Th和238U的平均放射性浓度分别为32.96±1.90、37.64±1.91和39.28±1.96 Bq kg−1,鱼类样品中226Ra、232Th和238U的平均放射性浓度分别为0.21±0.03、0.69±0.11和0.19±0.03 Bq kg−1,蛤蜊样品中226Ra、232Th和238U的平均放射性浓度分别为0.23±0.041、0.41±0.06和0.31±0.06 Bq kg−1。海水中的放射性浓度高于沉积物中的放射性浓度,也高于其他国家报告的放射性浓度。在海防、广宁和河静,鱼类样本的分布系数(L/kg)均值分别为0.53、0.13和0.23,蛤类样本的分布系数(L/kg)均值分别为0.19、0.16和0.13。此外,海防、广宁和河静的生态剂量分别为鱼类0.03、0.02和0.02µGy h - 1,蛤的生态剂量分别为0.02、0.03和0.03µGy h - 1,人类海鲜消费平均剂量率为1.13×10-6 Sv/年。对结果进行了讨论,并与类似研究报告的结果以及与科委会建议的范围内的国际推荐值进行了比较。

Assessing the radiological risks associated with primarily natural radioactivities of coastal seawater in northen Vietnam using the Erica software
The activity concentrations of naturally occurring radionuclides 226Ra, 232Th, and 238U were determined in marine sediments, seawaters and seafood along the Gulf of Vietnam to establish baseline data for future environmental monitoring at a surface water depth of 0–3 cm. The concentration of uranium, thorium and radium were determined using a low background gamma spectrum as well as activity ofy of 238U(214Bi), 232Th(228Ac) and 226Ra. The mean radioactivity concentrations of 226Ra, 232Th, and 238U were found to be 8.59 ± 0.54, 1.31 ± 0.15, and 6.91 ± 0.64 Bq m−3, respectively, in seawater samples and 32.96 ± 1.90, 37.64 ± 1.91, and 39.28 ± 1.96 Bq kg−1, respectively, in marine sediments, 0.21 ± 0.03, 0.69 ± 0.11, and 0.19 ± 0.03 Bq kg−1, respectively, in fish samples and 0.23 ± 0.041, 0.41 ± 0.06, and 0.31 ± 0.06 Bq kg−1, respectively, in clam samples. The radioactivity concentrations in seawater are higher than those in sediment and compared with those reported in other countries. The mean values of distribution coefficient (L/kg) is 0.53, 0.13, and 0.23, respectively, in fish samples and 0.19, 0.16 and 0.13, respectively, in clam samples at Hai Phong, Quang Ninh and Ha Tinh. Moreover, the ecological dose at Hai Phong, Quang Ninh and Ha Tinh are 0.03, 0.02 and 0.02 µGy h−1, respectively, in fish and 0.02, 0.03, and 0.03 µGy h−1, respectively, in clams and the mean human’s seafood consumers dose rate is 1.13×10-6 Sv/yrs. Results were discussed and compared with those reported in similar studies and with internationally recommended values within limits recommended by UNSCEAR.
