新疆阿勒泰地区矿产企业工作人员及公众辐射剂量估算

Estimation of radiation dose for workers and the public of mining enterprisesin Altay,Xinjiang

文章选取新疆阿勒泰地区9家有代表性的矿产企业,通过剂量估算模式估算了工作人员外照射和内照射剂量以及公众年有效剂量。发现阿勒泰地区矿产企业工作人员受到最大年附加有效剂量值为0.75mSv/a,由于装修使用石材所致公众所受最大年附加有效剂量为0.28mSv/a,均低于《电离辐射防护与辐射源安全基本标准》(GB18871-2002)限值的要求,希望本次研究能够为矿产资源开发利用的辐射环境研究和管理者提供基础数据。

In this paper, nine representative mineral enterprises in Altay region of Xinjiang were selected to estimate the external and internal radiation doses of staff and the annual effective dose of the public through the dose estimation model.It is found that the maximum annual additional effective dose to the staff of mineral enterprises in Altay is 0.75 mSv/a, and that of the public is 0.28 mSv/a due to stone decoration, which are all lower than the requirements of the basic standard for protection against ionizing radiation and safety of radiation sources(GB18871-2002).It is hoped that this study can be used for the study of radiation environment for the development and utilization of mineral resources And managers to provide basic data.
