阿坝州壤塘地区天然放射性水平评价
摘要
Abstract
EDS was used for spot measurement of natural radionuclide in Rangtang of Aba. The authors calculate internal / external exposure index, "y-ray exposure rate and y-ray external exposure, and appraise the natural radioactive environment of the region. The results showed that y-ray exposure rate was higher than the average of the country (100. 07Gy/h)and the world (80Gy/h) in the region. But internal / external exposure index, y-ray exposure rate and y-ray external exposure were in the range of the country control limits. Enrichment of surface water and transport of radioactive elements in the role of the soil pool area have an impact on the level of radioactivity. And the fault zone near the relatively high level of radioactivity. Rangtang natural radioactivity level of the region is still in a safe range, suitable for human living and life.关键词
