摘　　要：该研究全面地调查了铀矿石集散地放射性污染状况及动态，分析测定了久长车站及周围环境土壤、水源、粮食作物中铀、钍、镭及总α、总β放射性水平、站内外地表β、γ辐射强度，劳保用品、运输车辆的污染状况，水源及空气中氡的浓度。基本摸清了久长车站及周围地域的放射性水平、分布规律、动态变化及采取防护措施的效果。We have fully investisated the radioactive pollution condition and dynamic of uraninite collectingand distrlbuting centre, analysed and determined the radioactive levels of uranium, thoriurn. radium andtotal a and β in soil .water sources, crops of Jiuchang Railway Station and its environment, β, γ radiat ion intensity on the ground within or without Station，the pollution condition of labour insurance articl es and transportation vehicle，radon concentration in the water sources and air. We have almost foundout the radioactive levels， the distributive regulation, the dynamic change at Jiuchang Station and its esurroundings, and the results after using protective measures.
