Po is a significant source of ionizing radiation that people are exposed to through food globally. This paper presents the wide range of accumulation level of Po in the organs of two species of shellfish including freshwater mussel (Sinanodonta jourdyi) and golden apple snail (Pomacea canaliculata), common freshwater species in Vietnam. There was a significant correlation between Po activity in muscle to their mass and size of freshwater mussels. In contrast, there was no relation between other organs of both species with their mass and size. The annual effective dose due to consumption of freshwater mussels ranged from 68.7 to 291 μSv year with a mean value of 138 μSv year for muscle and from 321 to 4560 μSv year with a mean value of 1422 μSv year for the hepatopancreas. Meanwhile, the AED for golden apple snail was recorded to be higher with values ranging from 105 to 2189 μSv year with mean value of 673 μSv year for muscle and from 468 to 4155 μSv year with a mean value of 2332 μSv year for hepatopancreas. Thus, the consumption of these two types of shellfish is considered relatively safe, but the hepatopancreas gland must be removed before processing.
Po 是人们通过食物在全球范围内接触到的一种重要电离辐射源。本文介绍了两种贝类（包括淡水贻贝 Sinanodonta jourdyi 和金苹果蜗牛 Pomacea canaliculata）中 Po 的积累水平范围，这两种贝类是越南常见的淡水物种。Po 在肌肉中的活性与其质量和大小之间存在显著相关性。相比之下，两种贝类的其他器官与其质量和大小之间没有关系。由于食用淡水贻贝而导致的年有效剂量范围为 68.7 至 291 μSv 年，肌肉的平均值为 138 μSv 年，而肝胰腺的范围为 321 至 4560 μSv 年，平均值为 1422 μSv 年。同时，金苹果蜗牛的 AED 被记录为更高，肌肉的范围为 105 至 2189 μSv 年，平均值为 673 μSv 年，肝胰腺的范围为 468 至 4155 μSv 年，平均值为 2332 μSv 年。因此，食用这两种类型的贝类被认为是相对安全的，但在加工前必须去除肝胰腺。
