研究发现,当浓缩铀UO_2F_2单次或多次为机体摄入后,都观察到在体内蓄积最高的器官是肾脏,其次是骨骼,再则为肝脏,而在其余器官组织中含量甚微。实验观察表明,无论机体是单次或多次摄入浓缩铀,其在体内呈现的选择性蓄积特性与天然铀是一致的。 浓缩铀UO_2F_2在体内的蓄积动态是,在肾脏和肝脏中迅速出现蓄积高峰,并随观察时间的延长而逐渐降低。至于在骨骼中则随着观察时间的增长而持续升高。浓缩铀UO_2F_2诱发的血淋巴细胞畸变效应,可随摄入体内的剂量增大而血细胞畸变率亦增高。且可在一个细胞中观察到有两个畸变发生,同时细胞分裂指数亦受到明显抑制。
The study found that when uranium enriched uranium UO_2F_2 was taken into the body one or more times, it was observed that the organs that accumulate the most in the body were the kidneys, followed by the bones, then the liver, and the rest of the organs and tissues. Experimental observations show that, whether the body is uranium enriched uranium in single or multiple ingestion, its selective accumulation characteristics in vivo are consistent with those of natural uranium. The dynamic accumulation of uranium enriched uranium (UO 2 F 2) in vivo is the rapid accumulation peak in the kidney and liver, which gradually decreases with the prolongation of observation time. As in the bones, however, with the increase of observation time and continued to rise. The uranium-enriched uranium (UO 2 F 2) -induced hemolymph aberration can increase the aberration rate of blood cells with the increase of in vivo dose. Two aberrations were observed in one cell, and the cell division index was also significantly inhibited.
