研究了荧光涂料激发能源１４７Ｐｍ内污染机体时的滞留过程：发现仅在早期降低较快，以后的降低极为缓慢。估算的体内滞留方程为：Ｒ（ｔ）＝０．１９９ｅ－０．１４５２ｔ＋０．８１２ｅ－０．０００８ｔ，可见包括两个快慢组分的半滞留期，即Ｔ１＝４．１７ｄ，而Ｔ２＝８６６．３ｄ·１４７Ｐｍ内污染机体中，观察到可诱发外周血淋巴细胞ＳＣＥ率呈持续增升：当１４７Ｐｍ摄入机体后的不同间隔阶段，可见在各实验组淋巴细胞的ＳＣＥ率均明显高于对照组，尤其是到第３０ｄ的观察阶段，出现了一个与外周血淋巴细胞染色体畸变率相对应的ＳＣＥ率增升高峰值。
Fluorescent coatings were used to stimulate the process of pollutants in 147Pm contaminated air. It was found that the fluorescence coating only decreased rapidly in the early stage and then decreased very slowly. The estimated in vivo retention equation is: R (t) = 0.199e-0.1452t + 0.812e-0.0008t, showing a half-residence time consisting of two fast and slow components, T1 = 4.17d and T2 = 866. 3d · 147Pm contaminated body, observed that peripheral blood can be induced SCE rate showed a continuous increase: when 147Pm into the body at different intervals after the stage, we can see in each experimental group lymphocyte SCE rate were significantly higher than the control group , Especially in the observation period of the 30th day, a peak value of SCE increase corresponding to the chromosome aberration rate of peripheral blood lymphocytes appeared.
