摘要: 通过对煤矿实地调查获取的数据及相关文献进行综合分析,发现2013年我国发电用煤中天然放射性核素含量按煤的年产量加权均值,238U为29.2±2.9 Bq/kg、226Ra为25.2±2.1 Bq/kg、232Th为26.9±0.1 Bq/kg、40K为64.0±0.6 Bq/kg、210Po为20.7±0.2 Bq/kg、210Pb为24.6±0.3 Bq/kg;天然放射性核素含量按煤矿规模加权均值,238U为33.9±9.7 Bq/kg、226Ra为30.9±7.9 Bq/kg、232Th为28.5±4.2 Bq/kg、40K为79.7±20.4 Bq/kg、210Po为26.8±4.3 Bq/kg、210Pb为33.9±7.7 Bq/kg。本次调查结果可以为全面评价我国煤电产业链的放射性影响提供发电用煤天然放射性水平的基础数据。

Abstract: Based on the analysis of the data obtained from coal mines and related literature, it is found that in 2013, the natural radionuclide content of 238U, 226Ra, 232Th, 40K, 210Po, and 210Pb for coal samples is 29.2±2.9 Bq/kg, 25.2±2.1 Bq/kg, 26.9±0.1 Bq/kg, 64.0±0.6 Bq/kg, 20.7±0.2 Bq/kg and 24.6±0.3 Bq/kg respectively based on weighted average of annual production; while the natural radionuclides content for coal samples is 33.9±9.7 Bq/kg, 30.9±7.9 Bq/kg, 28.5±4.2 Bq/kg, 79.7±20.4 Bq/kg, 26.8±4.3 Bq/kg and 33.9±7.7 Bq/kg respectively based on the weighted average of coal mine scale. The results of this survey can provide basic data for a comprehensive evaluation of the radioactive impact of Chinese coal power industry chain on the natural radioactive level of coal power generation.

Key words: coal used for power generation, natural radionuclides, investigation and analysis
