摘要
通过蒙特卡罗模拟方法研究门架式铀矿石中铀含量在线测量装置探测效率空间分布,并通过实验验证了模拟方法的可靠性,结果显示:门架式铀矿石中铀含量在线测量装置的探测效率在垂直方向急剧下降,下降速度超过左右与前后方向;当前后超出5 m范围,其探测效率下降幅度更大;左右偏移对所有探测器的探测效率均有较大影响。研究结果有助于改进门架式铀矿石中铀含量在线测量装置的现场使用与校准。
This study employs the Monte Carlo simulation method to investigate the spatial distribution of detection efficiency for an overhead uranium ore content measurement device.The reliability of the simulation method is validated through experiments.The results indicate that the detection efficiency of the overhead uranium ore content measurement device sharply decreases in the vertical direction,with a greater decline rate than in the horizontal and forward-backward directions.Beyond a range of 5 meters in the front and rear directions,the reduction in detection efficiency is more significant.Lateral displacement has a significant impact on the detection efficiency of all detectors.The research findings contribute to improving the on-site usage and calibration of overhead uranium ore content measurement devices.
