Studies show that ²³⁵UO₂F₂ was chiefly localized in kidneys, then in skeleton and liver. Its radioactivity in skeleton rose steadily while the concentration in kidneys and liver droped. ²³⁵UO₂F₂ was difficult to pass through the blood- testes barrier. With 1 to 6 h contact period, only 1.4- 1.6% ²³⁵UO₂F₂ was found in the intact skin, but 41-54% in the abrasive skin. The dynamic retention of ²³⁵UO₂F₂ through intact or abrasive skins was also dominantly localized in kidneys, skeleton and liver. Accumulation of insoluble ²³⁵U₃O₈ in gastrointestinal tract was well described by a double- exponential- term expression. Values of retention were estimated for fast component T₁=0.34 d, and for relatively long term component T₂=4.05 d.
