一、引言为适应我国热释光个人剂量监测工作向自动化、集中化方向发展的需要,我们研制了这套半自动测量仪。该仪器中使用了单板微处理机,在测量过程控制、数据的记录和处理以及处理结果的打印输出等方面完全实现了自动化。由于国内目前尚无适于全自动测量用的热释光剂量计(TLD)卡片,本仪器中仍使用分立的TLD元件,因此,元件更换仍需人工操作。半自动装置对元件的种类和形状的适应性强,结构简单造价较低,适于个人剂量监测、环境监测及TLD元件性能研究等多方面应用。
I. INTRODUCTION In order to meet the need of automatic and centralized direction of personal dose monitoring of thermoluminescence in China, we have developed this semi-automatic measuring instrument. The instrument uses a single-board microprocessor that is fully automated in measurement process control, data logging and processing, and printout of processing results. Since there are currently no thermoluminescent dosimeters (TLD) cards suitable for fully automatic measurement, discrete TLD components are still used in the instrument. Therefore, component replacement is still subject to manual operation. Semi-automatic devices have strong adaptability to the types and shapes of components, simple structure and low cost, and are suitable for many applications such as personal dose monitoring, environmental monitoring and TLD component performance research.
