Abstract： The geographic distribution, γ-radiation level and specific activity of radionuclides of the bone-coal mines in Zhejiang Province were reported. The weighted average of γ-radiation dose rate of the bone-coal mines is 566 nGy/h for 107 main bone-coal mines. The weighted mean activity of 238U, 226Ra, 232Th and 40K in the samples are 949, 918, 34 and 554 Bq/kg for 171 samples of bone-coal, respectively. 作 者： 作者单位： 期 刊： 核技术（英文版） SCI Journal： NUCLEAR SCIENCE AND TECHNIQUES 年，卷(期)： 2005, 16(5) 分类号： X591 X837 Keywords： Bone-coal Natural radioactivity γ-radiation level Radionuclides【Natural radioactivity level of assoc】相关文章：
