摘要/Abstract

摘要： 为了解乌鲁木齐市辐射环境水平,监测了乌鲁木齐市周围环境空气中沉降物2017—2021年⁷Be、⁴⁰K放射性水平。结果表明:乌鲁木齐市沉降物中⁷Be的最大值为2.8 Bq/(m²·d),最小值为1.1 Bq/(m²·d),5年均值为1.94 Bq/(m²·d);⁴⁰K的最大值为1 050 mBq/(m²·d),最小值为104 mBq/(m²·d),5年均值为354.3 mBq/(m²·d);乌鲁木齐市沉降物中的⁷Be、⁴⁰K放射性水平处于正常天然放射性水平,且5年测值基本处于稳定状态。

Abstract: To understand the environmental radiation status in Urumqi, we monitored ⁷Be and ⁴⁰K levels in fallout from 2017 to 2021. It showes that the 5-year average of ⁷Be is 1.94 Bq/(m²·d), with the maximum of 2.8 Bq/(m²·d) and the minimum of 1.1 Bq/(m²·d). For ⁴⁰K, the results are 354.3, 1 050, and 104 mBq/(m²·d) respectively. Both radionuclides are at normal natural levels, and the 5-year measurements are basically stable.

Key words: fallout, ⁷Be, ⁴⁰K
