Abstract：
The study on natural radionuclides in edible bivalves from the Cochin backwater lagoon, Kerala, employing alpha spectrometry, revealed higher concentrations of 210Po and 210Pb compared to 238U and 232Th. The annual committed effective dose (ACED) for the adult coastal population was calculated at a range of 1494.9 to 5783.4 μSv y-1, with 210Po being the predominant contributor, responsible for about 85 % of the dose. This highlighted significant health risks, underscored by a calculated cumulative mortality and morbidity risk range between 5.23 × 10-3 and 2.02 × 10-2. These findings emphasized the need for further research and the development of regulatory measures to mitigate exposure risks.
摘要：
科钦回水泻湖食用双壳类动物中天然放射性核素的研究，喀拉拉邦,使用阿尔法光谱法，与238U和232Th相比，210Po和210Pb的浓度更高。成人沿海人口的年承诺有效剂量（ACED）的计算范围为1494.9至5783.4μSvy-1，主要贡献者为210Po，负责约85％的剂量。这突出了重大的健康风险，计算出的累积死亡率和发病率风险范围在5.23×10-3和2.02×10-2之间。这些发现强调了进一步研究和制定监管措施以减轻暴露风险的必要性。
