摘要
通过对某地区环境γ辐射空气吸收剂量率、大气氡浓度、地表氡析出率以及土壤氡浓度的测量,依据合适的估算模式,估算出该地区人均年吸收剂量率。对一个地区的放射性环境进行评价,划分出可开发区、限制开发区、污染区和源项,即能为有关部门制定国土规划、国土整治等提供可靠的放射性环境信息,并对污染区及源项提出合理的治理方案。
Through the measurements of environmental gamma-radiation absorbed dose rate,atmospheric radon concentration,surface radon exhalation rate and radon concentration in soil in a region,an appropriate estimation model was chosen to estimate per capita absorbed dose rate in the region.Based on the assessment of radiation in the region,the place can be divided into development area,limited development area,polluted area and source item area,and reliable information on radioactive environment can be provided for relevant departments formulating land planning and management.
