India is the second largest seafood producer in the world marketing more than 7000 edible species. In this regard, commendable studies have been conducted since the 1970s by different research groups and more data are reported. In this work, all the studies on 210Po and 210Pb measurements in abiotic and biotic components of India have been combined and reviewed. The concentrations of 210Po and 210Pb are estimated by radiochemical separation followed by alpha counting. Grain size, season, Tsunami waves and place of sampling have a decisive bearing on 210Po and 210Pb concentration in abiotic components. Plankton shows a higher Kd factor (104) compared to seaweeds and sea grass (103). Pond ecosystems recorded the highest Kd factor (4·3 × 104) compared to other freshwater and marine ecosystems. Bioaccumulation of 210Po and 210Pb varies with respect to variety of seafood. The committed effective dose (CED) calculated for shellfish species maintained a higher range of 2.5 × 10-2 mSv/y to 9.8 × 10-1 mSv/y and for fish species fluctuated from 3.8 × 10-4 mSv/y to 2.0 × 10-1 mSv/y. The studies conducted so far are scattered, and need to be gathered for future reference and planning (i.e. There is not much information available for Kerala, Karnataka, Maharashtra, Gujarat, Andhra, West Bengal and Odessa coast). Therefore, it is strongly recommended that further and more complete research is undertaken to study the bioaccumulation of 210Po and 210Pb from seafood. Overall, the present review concludes that Indian seafood is radiologically safe.
印度是世界第二大海产品生产国，销售的可食用海产品种类超过7000种。在这方面，自20世纪70年代以来，不同的研究团队开展了值得称赞的研究，并报告了更多数据。在这项工作中，对印度非生物和生物成分中210钋和210铅测量的所有研究进行了汇总和综述。210钋和210铅的浓度通过放射化学分离后进行阿尔法计数来估算。粒度、季节、海啸波和采样地点对非生物成分中210钋和210铅的浓度具有决定性影响。与海藻和海草（103）相比，浮游生物显示出更高的分配系数（104）。与其他淡水和海洋生态系统相比，池塘生态系统记录的分配系数最高（4·3×104）。210钋和210铅在各种海产品中的生物累积情况各不相同。为贝类物种计算的约定有效剂量（CED）保持在较高范围，即2.5×10-2毫希沃特/年至9.8×10-1毫希沃特/年，而鱼类物种的约定有效剂量则在3.8×10-4毫希沃特/年至2.0×10-1毫希沃特/年之间波动。迄今为止进行的研究较为分散，需要收集起来以供未来参考和规划（即喀拉拉邦、卡纳塔克邦、马哈拉施特拉邦、古吉拉特邦、安得拉邦、西孟加拉邦和奥里萨邦海岸可获取的信息不多）。因此，强烈建议开展进一步且更全面的研究，以研究海产品中210钋和210铅的生物累积情况。总体而言，本次综述得出结论，印度海产品在辐射方面是安全的。
