Abstract
A measurement has been made for the radioactivities (or concentrations) of radon daughters, i.e., RaA, RaB and RaC in airborne dust by means of single filtering method. This is to evaluate the radioactivities in terms of Ci or WL (working level) from gross alpha counts measured in the selected-time intervals after an air sample is taken from a membrane filter paper with a mean pore size of
단일집진법(單一集塵法)을 써서 공기부유진중(空氣浮游塵中)에 존재(存在)하는 라돈 붕괴생성물(崩壞生成物), 즉, RaA, RaB 및 RaC 의 방사능(放射能)(또는 농도(濃度))을 측정(測定)하였다. 이것은 단일집진장치(單一集塵裝置)를 이용하여 평균공격(平均孔隔)(mean pore size)이
