由于气溶胶颗粒具有一定的形状和大小，使得氡子体衰变发射的α粒子从气溶胶颗粒中穿出的过程存在着一定的能量损失。本文基于球外各向同性点源模型，利用蒙特卡罗方法进行编程计算，对氡子体气溶胶发射α粒子过程中的能量自吸收进行修正-As the aerosol particles have a certain shape and size , so that the decay of radon progeny of α particles emitted　the aerosol particles piercing process there is some energy loss. This paper ball outside isotropic point source model, using Monte Carlo methods programmed calculations for radon progeny aerosols emitted α particle self-absorption of energy in the process of correction .
