摘要
钢渣中含有226 Ra、232 Th、40 K等多种天然放射性核素,在其综合利用时放射性检测是必要的。通过简述钢渣的利用现状,分析钢渣天然放射性的来源及其危害,阐述钢渣辐射检测的必要性,提出钢渣放射性水平控制的主要措施并展望其发展前景。
Steel slag contains^226 Ra,^232Th, ^40K and other natural radioactive elements,so the detection of radioactivity is necessary when it is widely utilized. By summarizing the utilization status of steel slag〉 the source and harm of radio-activity in steel slag were analyzed and the necessity of steel slag radiation detection was explained, then we put forward the main measures of steel slag radioactive level control and its development prospect.
