Abstract

Optically-stimulated luminescent dosimeters are capable of being interrogated multiple times post-irradiation. Each interrogation removes a fraction of the signal stored within the optically-stimulated luminescent dosimeter. This signal loss must be corrected to avoid systematic errors in estimating the average signal of a series of optically-stimulated luminescent dosimeter interrogations and requires a minimum number of consecutive readings to determine an average signal that is within a desired accuracy of the true signal with a desired statistical confidence. This paper establishes a technical basis for determining the required number of readings for a particular application of these dosimeters when using certain OSL dosimetry systems.

摘要

光激发发光剂量计在辐照后能够被多次读取。每次读取都会去除光激发发光剂量计中存储信号的一部分。必须对这种信号损失进行校正，以避免在估计一系列光激发发光剂量计读取的平均信号时出现系统误差，并且需要最少数量的连续读数来确定一个平均信号，该平均信号在具有所需统计置信度的情况下处于真实信号的所需精度范围内。本文为在使用某些光激发发光剂量测定系统时确定这些剂量计特定应用所需的读数数量建立了技术基础。
