摘要
在开展城市地质工作中、我队于1986年起对大连地区1632km2的面积开展了地面放射性测量,在此基础上对γ辐射水平作了信息转换,从而扩大了以往仅应用于地质工作中的放射性γ测量的服务领域,提高了放射性测量的应用效果。本文详细介绍了大连地区天然环境γ辐射水平及其空气吸收剂量的分布特征。编制了《大连地区天然环境电离辐射照射量率分区图》和《大连地区天然环境电离辐射空气吸收剂量率分布图》。该项工作的完成,为大连市提供了环境放射性背景资料,为物化探工作服务于城市环境迈出了可喜的一步。
Abstract
For the purpose of extending the urban geological work, our party has conducted since 1986 ground radiometric measurement over an area of 1632 km2 in Dalian and, on such a basis, made information conversion for gamma radiation level, thus extending the service of radiometric measurement which was formerly only used in geological work, and raising the effectiveness of ra-diometric measurement.This paper describes in detail the natural environment gamma radiation level of Dalian area and distribution of air-absorbed doses. Two maps, namely. the division of natural eivironment ionizing radiation ra tes in Dalian area and the distribution of air-absorbed doses of natural envi ronment ionizing radiation, have bean compiled.
The completion of this work has provided environmental radiogenic ba ckground data for Dalian City and made a gratifying stride in applying geo physical and geochemical prospecting to the study of urban environment.
