在处理含钍矿石的厂矿中,(气土)子体对人主要危害是吸入呼吸道内对人体产生内照射,其中主要是由(气土)子体在衰变过程中放出的α粒子的能量所致。(气土)子体的α潜能系指单位空气中的(气土)子体原子完全衰变到ThD过程中所释放的α粒子能量的总和。它是直接反映被(气土)子体沾染的空气危害程度的一个有用指标。因此测量(气土)子体的α潜能值比测量它的浓度值更具有实
In the factories and mines dealing with thorium ores, the main hazard to humans is the inhalation of the respiratory tract to produce internal radiation on the human body, which is mainly caused by the (alpha) particle energy released by the (gas and soil) To The α-potential of a (so-called soil) progeny is the sum of the energy of the alpha particles released during the complete decay of (air-earth) daughter-body atoms in the unit of air to ThD. It is a useful indicator that directly reflects the degree of air damage that is contaminated by the (Earth) sub-population. It is therefore more realistic to measure the [alpha] potential of a (soils) progeny than to measure its concentration
