本文探讨短寿命氡子体从家兔肺内的廓清。对吸入氡子体的家兔,通过体外γ计数测量,观察RaB 从其肺内的清除速率。实验结果表明,RaB 从家兔肺内廓清的生物半排期约为6.4h。
This article explores the clearance of short-lived radon progeny from the lungs of rabbits. For rabbits inhaled with radon progeny, clearance rates of RaB from their lungs were observed by in vitro gamma counting. The experimental results show that the biological half-life of RaB from rabbit lung clearance is about 6.4h.
