Concentration factors for technetium recommended in radiological assessment models for freshwater biota are default values based on the behavior of iodine in the environment. In this study a small experimental freshwater pond was spiked with 95mTc to obtain data for calculating concentration factors for fish and snails. A model using the pond data was developed to calculate steady-state body burdens for freshwater biota. The concentration factors based on the calculated body burden for carp (Caprinus carpio), mosquitofish (Gambusia affinis), and snails (Helisoma sp.) were 11, 75 and 121, respectively. The concentration factor for carp was less than the recommended value of 15 listed in the USNRC Regulatory Guide 1.109 for calculating radiation dose to man; however, the concentration factors for mosquitofish and snails exceeded the recommended values by 5 and 24 times, respectively.
放射评估模型中为淡水生物群推荐的锝浓缩系数是基于碘在环境中的行为的默认值。在本研究中，一个小型实验淡水池塘被注入了95mTc，以获取计算鱼类和蜗牛浓缩系数的数据。利用池塘数据开发了一个模型，以计算淡水生物群的稳态体内负荷。基于计算得出的鲤鱼（Cyprinus carpio）、食蚊鱼（Gambusia affinis）和蜗牛（Helisoma sp.）的体内负荷的浓缩系数分别为11、75和121。鲤鱼的浓缩系数低于美国核管理委员会监管指南1.109中列出的用于计算人体辐射剂量的推荐值15；然而，食蚊鱼和蜗牛的浓缩系数分别比推荐值高出5倍和24倍。
