一、引言近10年来,辐射化学的发展是惊人的。世界各国一些强辐射源(包括CO~(60)辐射源,加速器及辐射反应堆)的建立,使辐射化学工作跨入新的里程。而准确的剂量测定是辐射化学研究的基础,对辐射化学来说,了解一个辐射源在某一地点对某物质所产生的效应,常常要比辐射源本身的强度来得重要。根据目前剂量测量发展的情况来看,化学剂量法已成为剂量方面的最主要的方法之一,也是最有前途的方法。目前采用的亚铁剂量计是一种快速而又可靠的剂 I. Introduction In recent 10 years, the development of radiation chemistry has been phenomenal. The establishment of some strong radiation sources (including CO ~ (60) radiation sources, accelerators and radiation reactors in various countries in the world) has brought radiochemical work to a new milestone. Accurate dosimetry is the basis of radiation chemistry, and for radiation chemistry it is often more important to understand the effect of a source on a substance at a given location than the intensity of the source itself. According to the current situation of dose measurement development, the chemical dose method has become one of the most important dose methods, but also the most promising method. Ferrous dosimeters currently used are a fast and reliable agent
