摘要: 210Po、210Pb是天然放射性核素,是天然照射的重要来源。空气中的210Po、210Pb主要附着在颗粒物上。本工作通过对我国环境气溶胶中210Po、210Pb取样测量,对我国空气中210Po、210Pb浓度水平做了初步的分析。我国环境气溶胶中210Po、210Pb的浓度水平普遍高于国外水平。

关键词: 210Po, 210Pb, 空气, 活度浓度

Abstract: As natural radionuclides, 210Po and 210Pb are important sources for natural exposure, generally being attached to the particulates in air. In order to analyze the activity concentration distribution of airborne 210Po and 210Pb in China, environmental aerosols were sampled and assayed. The results showed that the activity concentrations of airborne 210Po and 210Pb in China were generally higher than those in other countries.

Key words: 210Po, 210Pb, air, activity concentration
