大庆石油管理局测井公司放射源库及周围环境的放射性水平调查

Investigation on Radioactivity Levels of Radioactive Source Storehouses and Surrounding Environment in Logging CO.of Daqing Petroleum Administrative Burear

对大庆测井公司放射源库及周围环境的放射性水平进行了调查,调查内容分为环境空气气溶胶辐射水平、水环境辐射水平、环境地表γ辐射空气吸收剂量率及土壤环境辐射水平四个方面。监测调查结果表明：源库内和源库外总α、总β监测值与对照点比较,均没有显著性差异,说明空气中的环境是安全的;放射源库周围水环境总α、总β监测值符合相应标准规定,说明水环境未受到放射性污染;γ辐射空气吸收剂量率监测值范围均在黑龙江省室外天然本底值21.6×10^-9-196.9×10^-9Cy/h范围内,说明放射源库室外地区未受到放射性污染;土壤监测值与黑龙江省土壤放射性水平进行了对比,也未发现放射源库周围土壤环境受到放射性污染。总之,大庆石油管理局测井公司放射源库未形成对周围环境及人群健康的不良影响。

The investigation on radioactivity levels of radioactive source storehouses and surrounding environment were conducted in logging CO. of Daqing Petroleum Administrative Burear. The investigating content was divided into four aspects i. e. radiation level of airborne aerosol, radiation level of water environment, γ - radiation dose rates of environment＇s surface and radiation level of soil environment. The results shows that the monitoring Total α value and the monitoring Total β value between internal and external radioactive source storehouses from control area, there were not obvious difference between control area, then it proved that environment in air is safety; Both the monitoring Total α value and the monitoring Total β value of radioactive source storehouses accorded with the corresponding standard rule, then it proved that surrounding water environment of radioactive source storehouses was not polluted by radioactivity ; The monitoring value of γ- radiation dose rates were within the natural background level of Heilongjiang province＇s outdoor which ranged from 21.6 × 10^-9 - 196.9 × 10^-9 Cy/h, then it proved that outdoor region of radioactive source storehouses was not polluted by radioactivity ; The monitoring value of soil was compared with radioactivity level of soil in Heilongjiang province, then it proved that surrounding environment of radioactive source storehouses was also not polluted by radioactivity. In a word, the radioactive source storehouses in Logging CO. of Daqing Petroleum Administrative Burear has not exercised adverse surrounding environment and health effec.
