随着医学科学的发展,X线成了医疗保健工作中的重要诊断方法之一,在许多国家,医疗照射即X线诊断检查已成为居民群体剂量的最大来源,为减少受检查的照射剂量,国内外对X线透视和摄影的照射量日益重视。本文采用国产氟化锂[LiF(Mg、Cu、P)]热释光剂量计(TLD),在X线诊断机上进行实验测试,检验热释光剂量计的灵敏度、精确度和临床应用价值,现介绍如下。材料与方法1．仪器:(1)X线机:800mA、150kV三相12波全波整流X线机,焦点0.6/1.2mm的旋转阳极X线管。
With the development of medical science, X-ray has become one of the most important diagnostic methods in the medical and health care work. In many countries, X-ray diagnosis of medical radiation has become the largest source of population dose. In order to reduce the radiation dose under examination, Domestic and foreign X-ray and photographic radiation exposure day by day. In this paper, domestic lithium fluoride (LiF (Mg, Cu, P)] thermoluminescence dosimeter (TLD) was used in the experiment to test the sensitivity, accuracy and clinical value of the thermoluminescence dosimeter. Now introduced as follows. Materials and methods 1. Instrument: (1) X-ray machine: 800mA, 150kV three-phase 12-wave full-wave rectifier X-ray machine, the focus of 0.6 / 1.2mm rotating anode X-ray tube.
