核电站产生的大量氚主要以氚水的形式释放到环境中,并通过食物链被摄入到人体.因此,人体可受到氚水和氚化有机化合物两种形式的氚照射.六种氚化有机化合物以长期饮水的方式使大鼠受照,并对他们进入动物组织后的结合行为及辐射剂量进行了研究和估算.实验用3～4月龄的雄性Wister大鼠.五只一组分四组和三只一组的分三组.前四组分别给予~3HHO(氚水)、L-4,5〔~3H〕亮氨酸(185GBq/
The bulk of the tritium produced by nuclear power plants is released into the environment mainly in the form of tritiated water and taken up to the human body through the food chain and thus the body can be exposed to both forms of tritium, tritiated water and tritiated organic compounds.6 Six tritiated organic compounds Rats were exposed to long-term drinking water, and their binding behavior and radiation dose after entering the animal tissues were studied and evaluated.Male Wister rats aged 3 ~ 4 months were divided into four groups And three groups were divided into three groups.The first four groups were given ~ 3HHO (tritiated water), L-4,5 〔~ 3H〕 leucine (185GBq /
