某铀矿氡及氡子体浓度和γ照射量率的调查与研究
INVESTIGATION AND STUDY ON CONCENTRATION OF RADON AND ITS PROGENE, AND γ EXPOSURE RATE IN CERTAIN URANIUM MINE
【摘要】 调查研究了某铀矿区内氡及氡子体浓度和γ照射量率。结果表明该矿井下平均氡浓度为６．８７×１０３Ｂｑ·ｍ－３，氡子体ａ潜能浓度为１４５１．２７×１０－８Ｊ·ｍ－３，γ照射量率为６．７２Ｃ／ｋｇ·ｈ。矿区地表、生活区和外围区平均氛浓度为１５．４０Ｂｑ·ｍ－３，氧子体ａ潜能浓度为８．９５×１０－８Ｊ·ｍ－３，．γ照射量率为０．４５Ｃ／ｋｇ·ｈ。
【Abstract】 The investigation result on radiation level in certain uranium mine was given in this paper. The radon concentration and a potential energe of radon progene in mine were 6.87×103Bq.m-3 and 1415.27×10-8J·m-3 respectively. The γ exposure rate in mine was 6.72 C/kg.h. The concentration of radon and its progene and γ exposure rate in mine surface, living area and its surroundings, were 15 .40 Bq.m-3, 8. 95 × 10-8J.m-3 and 0. 45 C/kg.h respectiyely.
