【摘要】 行李放射性检测装置可与现有X射线安全检测装置联合用于放射性安全检测。该装置采用NaI(Tl)探测器,用移动平均法进行放射性检测。在本底为0.1μGy/h、行李移动速度小于0.2 m/s条件下,该装置对137Cs6、0Co1、33Ba核素的可探测活度下限分别为6.7×103、3.7×103、6.7×103Bq,对富集度为90%的U样品,探测质量下限为2 g。更多还原

【Abstract】 The luggage radiation monitor with NaI（Tl） detector can combined with X-ray monitor to be used for radioactivity monitoring in railway station and airport.The moving average detection method is used for the monitor.At the background intensity of 0.1 μGy/h and the moving speed of 0.2 m/s,the sensitivity of the monitor is 6.7×10³,3.7×10³, 6.7×10³ Bq,respectively for ¹³⁷Cs,⁶⁰Co,¹³³Ba radiation source,and the sensitivity is about 2 g for high enrichment uranium.更多还原
