新疆乌鲁木齐市放射性水平调查

Investigation of Radioactivity Level in Urumqi

为建立公众相关的放射性本底数据库,掌握环境介质的放射性水平和变化趋势,科学评价放射性水平及对人群健康效应的影响,新疆辐射环境监督站持续开展了对乌鲁木齐市周围环境介质放射性监测工作。本文给出了2013—2017年乌鲁木齐市气溶胶、沉降灰、土壤和地表水、饮用水中放射性核素水平以及γ瞬时剂量率和γ累计剂量的调查测量结果。调查结果表明乌鲁木齐市天然放射性水平处于本底范围内,这对掌握乌鲁木齐市放射性水平提供了科学依据。

In order to establish a radioactivity background database related to the public,grasp the radioactivity level of environmental media and its changing trend,and scientifically evaluate the radioactivity level and its impact on people's health,Xinjiang Radiation Environmental Monitoring Station has continuously carried out radioactivity monitoring of environmental media around Urumqi.This paper presents the survey and measurement results of the levels of radionuclides in aerosols,subsidence ash,soil and surface water,and drinking water,as well as the instantaneous dose rate and cumulative dose ofγin Urumqi from 2013 to 2017.The investigation results show that the natural radioactivity level in Urumqi is in the background range of the whole Xinjiang,which provides a scientific basis for mastering the radioactivity level in Urumqi.
