영문 초록

Radon progenies existing in indoor air were measured with α spectrometry. The concentrations of 218po, 214Pb, 214Bi and their unattached fractions inside the experimental chamber and Young Kwang Atomic Power Plant were measured with a relative standard deviation of below 50% after the analysis of α spectrum. The results Were compared with the other instrumental methods such as total α count and WL meter. The concentration of radon and the indoor condition were changed intentionally inside the chamber to study the behaviour of radon and radon daughters. Airborne particulates such as tobacco smoke increase equilibrium factor(EF, a major factor of the risk caused by radon) from 1.7 to 2.4 depending on indoor tobacco smoke concentrations. Unattached ratio which is also a important factor for the risk assessment of radon is inversely related to the concentration of indoor tobacco smoke.
