【摘要】 本文阐述了新研制的“放射性气溶胶自动监测仪”设计原理、功能和技术指标。该仪器采样、测量和数据处理均全自动化,其最小可检出水平:用样品放射性活度表示,对β为54mBq,当采样量为10m³时,可检出浓度为5.4mBq/m³(1.46×10^-16Ci/L);对于α可达3.6mBq,若采样量为10m³时,可检出浓度为0.36mBq/m³(9.7×10^-18Ci/L)。更多还原

【Abstract】 This paper describes the new development of the automatic monitor for radioactive aerosol,including designing principles,functions and technical specifications. The monitor is fully automatic in sampling,measurement and data-processing, Minimum detectable (3 activity is 54mBq.When the sampling volume is 10m3,the minimum detectable concentration is 5.4 mBq/ms(l.46X 10-le Ci/L).The minimum detectable oc activity is 3.6 mBq.When the sampling volume is 10m3,the minimum detectable concentration is 0.36mBq/m3(g.7X 10-18 Ci/L).更多还原
