Investigation and evaluation of radioactive environment in a bone coal mine area in Xiushui County, Jiangxi Province
摘要
Abstract
The development and comprehensive utilization of bone coal may cause certain pollution to the environment including the increased environmental radioactive level and radiation dose to the residents.Combined with multi-media sampling analysis,gamma dose rate field monitoring and ground gamma-ray spectrometry,the relationship between radionuclide distribution and environmental gamma dose rate of a typical bone coal mine in Xiushui County were investigated,and radiation dose to the residents in the mining area was estimated.The results showed that the average ground-level gamma dose rate up to 662 nGy/h has been reached,where the uranium deposit is mainly in the form of carbon silicon mudstone type.The measured activities of radionuclides in bone coal,bone-coal cinder,soil and water samples in this area were higher than the corresponding background values in the province.The effective dose to the surrounding residents was greater than 1 mSv per year.Radiation monitoring and control for bone coal mining is required.关键词
