在生产实践中,呼吸道是放射性核素进入体内的主要途径。放射性核素~(147)Pm进入肺区间后,在该区间沉积量和向血液转移速率,是评价该核素毒性的重要依据之一。本研究工作初步观察了~(147)Pm进入大鼠肺区间后,在肺区间沉积量和向血液转移速率的变 In production practice, the respiratory tract is the main way for radionuclides to enter the body. Radionuclide ~ (147) Pm into the lung interval, the amount of deposited in the interval and the rate of blood transfer is one of the important basis for the evaluation of the nuclide toxicity. In this study, we first observed the change of the amount of deposition and the rate of blood transfusion in the pulmonary region after ~ (147) Pm entering the lungs of rats
