【摘要】：石煤的開發(fā)和綜合利用對環(huán)境有可能造成一定的污染,其中影響環(huán)境放射性水平增高和居民受照劑量增加等輻射方面的污染問題較為敏感以及突出。本次研究對江西省主要石煤資源區(qū)——修水縣一處典型石煤礦的放射性環(huán)境進(jìn)行調(diào)查,通過多介質(zhì)采樣分析以及現(xiàn)場監(jiān)測γ輻射空氣吸收劑量率和地面γ能譜相結(jié)合,綜合研究該區(qū)放射性核素分布與環(huán)境γ劑量率之間的關(guān)系,利用公式估算石煤礦區(qū)居民輻射劑量并評價其環(huán)境輻射情況。結(jié)果表明,調(diào)查范圍內(nèi)的石煤礦區(qū)地面γ輻射空氣吸收劑量率的平均值達(dá)到了662 n Gy/h,該處鈾礦主要形式為碳硅泥巖型,區(qū)內(nèi)石煤、石煤渣、土壤、水樣放射性核素測量值都高于省內(nèi)相應(yīng)介質(zhì)的本底值,石煤礦的開采需接受專業(yè)的監(jiān)管。
[Abstract]:The exploitation and comprehensive utilization of stone coal may cause certain pollution to the environment, among which the radiation pollution problems such as the increase of environmental radioactivity level and the increase of radiation dose to residents are more sensitive and prominent.In this study, the radioactive environment of a typical stone coal mine in Xiushui County, a major stone coal resource area in Jiangxi Province, was investigated. By means of multi-medium sampling analysis and on-site monitoring of 緯 -radiation air absorption dose rate and surface 緯 energy spectrum,The relationship between the distribution of radionuclides and the environmental 緯 dose rate in this area is studied synthetically. The radiation dose of residents in the coal mining area is estimated by the formula and the environmental radiation is evaluated.The results show that the average absorbed dose rate of 緯 -radiation air in the stony coal mining area is 662 n Gy / h, where the uranium deposit is mainly of carbon-silicon mudstone type, stone coal, stone cinder, soil, etc.The measured values of radionuclides in water samples are higher than the background values of the corresponding media in the province, and the mining of stone coal mines should be subject to professional supervision.
