The scintillator detectors are recalibrated against the datasheet given by the manufacturer. Optimal and mutual dependent values of (a) high voltage at PMT (Photomultiplier Tube), (b) amplifier gain, (c) average time to count the radiation particles (set by operator), and (d) number of instances/sample number are estimated. Total 5: two versions of Central Limit Theorem (CLT), (3) industry preferred Pulse Width Saturation, (4) calibration based on MPPC coupled Gamma-ray detector, and (5) gross method are used. It is shown that the CLT method is the most optimal method to calibrate the detector and its respective electronics couple. An inverse modeling-based Computerized Tomography method is used for verification. It is shown that statistically averaging results are more accurate and precise data than mode and median if the data is not skewed and a random number of samples are used during the calibration process. It is also shown that the average time to count the radiation particle is the most important parameter affecting the optimal calibration setting for precision and accurate measurements of gamma radiation.

校准方法的灵敏度分析和影响辐射测量统计性质的因素

闪烁体探测器根据制造商提供的数据表重新校准。(a) PMT(光电倍增管)的高电压、(b) 放大器增益、(c) 计算辐射粒子的平均时间(由操作员设置)和 (d) 实例数/样本数的最佳和相互依赖值估计。共5个:两个版本的中心极限定理(CLT),(3)行业首选的脉宽饱和度,(4)基于MPPC耦合伽玛射线探测器的校准,以及(5)使用了粗略的方法。结果表明,CLT 方法是校准探测器及其各自电子偶的最佳方法。使用基于逆向建模的计算机断层扫描方法进行验证。结果表明,如果数据不偏斜且在校准过程中使用随机数量的样本,则统计平均结果比众数和中位数更准确和精确。还表明,对辐射粒子进行计数的平均时间是影响伽马辐射精确测量的最佳校准设置的最重要参数。
