半导体剂量仪是六十年代发展起来的一种新型辐射测量手段,较之其它测量方法有独到之处,在北欧、西欧一些国家首先投入临床使用。近十年来北欧的物理学家针对使用中出现的问题从理论上进行了深入的探索,并有效地改革了工艺,使其获得更大范围的普及,目前已进入国内市场,在少数放疗部门开展应用。对任何一种新的测量方法都要深入了解才能更 Semiconductor dosimeter is a new type of radiation measurement developed in the 1960s. Compared with other measurement methods, semiconductor dosimeter is the first to be used clinically in some countries of North Europe and Western Europe. In the past ten years, Nordic physicists have carried out in-depth theoretical exploration of the problems that have arisen in use and have effectively reformed the technology so that it can be popularized in a broader scope. Now it has entered the domestic market and is operating in a few radiotherapy departments application. For any new measurement method should be in-depth understanding to be more
