Objective To evaluate the biological effect of a kind of protective cover against inhalation of depleted uranium (DU) dust particles. Methods At 1 and 3 d after inhalation of DU dust particles, uranium concentrations in the blood, lung, bronchia, kidney, and liver of the rats in the protected group and non protected group were measured and the efficiency of protection was calculated. Results Uranium levels in all tissues and fluids of the rats in the protected group decreased significantly to 71.2%-96.1% as compared with those in non protected group. Conclusion The protective cover is effective to reduce the harm due to inhalation of DU dust particles.
