摘要
在许多场合都要求及时快速地给出污染环境中的气溶胶浓度,国内外的α/β放射性气溶胶监测仪大多采用连续测量方法,本文就α/β放射性气溶胶监测技术的研究进展进行了综述,分析了提高监测灵敏度的具体措施及其效果,为今后大气中α/β放射性的日常环境监测和应急事件防范工作提供了参考。
It is demanded to detect α/β radioactive aerosol concentration promptly in the contaminative air in many circumstances. Most of α/β radioactive aerosol monitors adoptcontinuo us measurements at present. In this article, the devel opment of α/β radioactiveaerosol monitoring techniques are summarized, and the methods of improving mornitoring sensitivity aswell as their effects are analysed. It supplies references for future daily environ mental measurement and the preventions from radioactive accidents.
