天津市大气气溶胶中7Be、210Pb和210Po活度浓度水平及辐射剂量评估

摘要/Abstract

摘要： 为了研究天津市大气气溶胶中⁷Be、²¹⁰Pb和²¹⁰Po活度浓度水平及其对公众产生的辐射剂量,预防辐射损伤的发生,本文对天津市2018—2020年总悬浮颗粒物(TSP)中⁷Be、²¹⁰Pb和²¹⁰Po进行检测分析。结果表明,天津市TSP中⁷Be、²¹⁰Pb和²¹⁰Po的年均活度水平分别为0.74~15.0 mBq/m³、0.21~2.5 μBq/m³和0.17~0.74 μBq/m;三种放射性核素的活度浓度均呈冬季最高,这是冬季高纬度冷空气和取暖季较高污染排放共同作用的结果;⁷Be、²¹⁰Pb和²¹⁰Po以吸入方式对公众产生的总有效待积剂量在6.28~40.1 μSv/a,低于公众照射规定的剂量限值(1 mSv/a),还不足以威胁人体健康。

Abstract: In order to study the activity concentration and to estimate the committed effective dose through inhalation of ⁷Be, ²¹⁰Pb and ²¹⁰Po in the atmospheric aerosols of Tianjin, TSP samples from 2018 to 2020 were analyzed. Activity concentrations of ⁷Be,²¹⁰Pb and ²¹⁰Po in TSP were in the range of 0.74-15.0 mBq/m³, 0.21-2.5 μBq/m³ and 0.17-0.74 μBq/m³, respectively. The activity concentrations of three radionuclides were at highest in winter. This is the combined effect of the airflow from high latitudes and the increased pollution emission in winter season in Tianjin. The total committed effective dose caused by ⁷Be, ²¹⁰Pb and ²¹⁰Po was in the range of 6.28-40.1 μSv/a, which was far lower than the dose limits for public exposure and not enough to threaten human health.

Key words: ⁷Be, ²¹⁰Pb, ²¹⁰Po, committed effective dose, Tianjin
