A study was made of the distribution of plutonium-239 within the rat body after single intragastric administration thereof (1.85 MBq) in a mixture with tributyl phosphate (TBP) and as Pu(IV) nitrate at a time interval from 4 min to 512 days. It was shown that the distribution of the radionuclide was virtually the same but its absorption from the gastrointestinal tract with Pu-TBP was higher by one order of magnitude and exceeded the value recommended by ICRP for soluble plutonium compounds.
对大鼠单次经胃给予钚 - 239（1.85 兆贝可）后，在 4 分钟至 512 天的时间间隔内，研究了其在大鼠体内与磷酸三丁酯（TBP）混合并以硝酸钚（IV）形式存在时的分布情况。结果表明，放射性核素的分布基本相同，但钚 - TBP 从胃肠道的吸收比 ICRP 推荐的可溶性钚化合物的值高一个数量级。
