TRANSFERENCE AND ACCUMULATIVE PECULIARITY OF ENRICHED URANIUM IN ORGANISM

TRANSFERENCE AND ACCUMULATIVE PECULIARITY OF ENRICHED URANIUM IN ORGANISM 1 first-author 1 1 Suzhou Medical College, Suzhou 215007, China Suzhou Medical College, Suzhou 215007, China Studies show that 235 UO 2 F 2 was chiefly localized in kidneys, then in skeleton and liver. Its radioactivity in skeleton rose steadily while the concentration in kidneys and liver droped. 235 UO 2 F 2 was difficult to pass through the blood- testes barrier. With 1 to 6 h contact period, only 1.4- 1.6% 235 UO 2 F 2 was found in the intact skin, but 41-54% in the abrasive skin. The dynamic retention of 235 UO 2 F 2 through intact or abrasive skins was also dominantly localized in kidneys, skeleton and liver. Accumulation of insoluble 235 U 3 O 8 in gastrointestinal tract was well described by a double- exponential- term expression. Values of retention were estimated for fast component T 1 =0.34 d, and for relatively long term component T 2 =4.05 d.
