摘　　要：采用径迹蚀刻方法探讨吸入的氡子体在大鼠气管内的沉积分布 ,结果表明 ,氡子体在气管内的沉积分布是不均匀的 ,近分叉处的沉积较多。此外 ,氡子体不完全沉积在上皮表面上 。The deposition distribution of inhaled radon daugh ters in rat tracheas is investigated using track etching method. The results ind icate that the deposition distribution of radon daughters in the tracheas is inh omogeneous and is higher in the region of branching. In addition, radon daughter s are not all deposited in a surface of epithelium, and a part of it is deposite d in different depth within epithelium.$$$$(
