摘　　要：本文用闪烁法及马尔科夫法测定了521间房屋的室内氡及子体浓度。其氡浓度算术均值为22.7Bqm^(-3),几何均值为16.3Bqm^(-3);子体潜能算术均值为6.02mwl,几何均值为3.94mwl,室内氡浓度遵从对数正态分布规律。人均年吸收剂量当量为1.05msv。This paper presents the results of a survey of indoor radon and its progeny conc. in 521 houses built with different building materials. The Scintillation and Markov methods were used. The arithmetic and geometric means of the indoor radon cone. were 22.7Bqm and 16.3Bqm respectively. The arithmetic and the geometric means of the radon progeny conc. were 6.02 mwl and 3.94 mwl respectively. The indoor radon cone. measurements were found to be normally distributed. The individual annual affective dose equivalent is 1.05 msv.
