安徽省歙县石煤矿区天然放射性环境调查

Abstract

Abstract: The γ-radiation air absorbed dose rate and radon concentration were measured in the She County coal mine area of Anhui Province, and the environmental media (soil, rock, stone coal, coal slag, coal gangue, sediment, surface water and groundwater) were systematically collected and analyzed. The results showed that the average gamma dose rate in the mine region is 121.5 nGy/h, which is much higher than the background value of Anhui Province and entire China. The gamma radiation level is controlled by the stratum/lithology, and the high value points are concentrated in bone coal mine. The mean concentrations of indoor and outdoor radon were 116.8 Bq/m³ and 47.1 Bq/m³ respectively, which were significantly higher than the background level. The concentration of ²³⁸U and ²²⁶Ra in bone coal, coal slag, coal gangue and carbonized brick is high, and the internal and external exposure index of carbonized bricks exceeds the radionuclide limit of building materials, so it is strictly prohibited to use them as main building materials. The development of bone coal has caused a significant increase in the concentration of radionuclides in the surrounding river sections, and the total α in the mine water exceeds the sewage discharge limit. Therefore supervision should be strengthened.

Key words: stone coal, natural radioactivity, γ dose rate, She Country
