The distribution of 239PuO2 (241Am) and BeO (7BeO) within the lungs of rats and dogs after the intratracheal administration was found to follow a normal law. The amplitude of deposition variations reached 98 per cent of the amount administered. It is recommended to group the experimental animals by individual deposition estimates.
气管内给药后，大鼠和犬肺内239PuO2（241Am）和BeO（7BeO）的分布符合正态分布规律。沉积变化幅度达到给药量的98%。建议根据个体沉积估计对实验动物进行分组。
