Abstract

Most buildings use decorative materials that are aesthetically pleasing, that may contain various amounts of radioactive elements. Thus, the human health of dwellers and workers is continuously exposed to ionizing radiation. Natural radioactivity (238U, 232Th, and 40K) is measured in decorative materials collected from different Iraqi local markets by utilizing a shielded high counting efficiency NaI(Tl) system. Some radiological hazard indexes in all samples were calculated. The results obtained showed that the maximum value of specific activity for 238U, 232Th, and 40K is in decorative stone and the minimum is measured in decorative alabaster. This study concluded that the natural radioactivity and radiological hazard in most samples of decorative materials were within the permissible limits by the United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR), the International Commission on Radiological Protection (ICRP), Organization for Economic Co-operation and Development (OECD), and other world reported. Therefore, most samples of decorative materials in the present study can be used without health risks according to radiation scope.

伊拉克一些装饰材料的天然放射性及其辐射危害评价

大多数建筑使用美观的装饰材料，这些材料可能含有不同数量的放射性元素。因此，居民和工人的人体健康持续暴露于电离辐射之下。天然放射性(238U, 232Th和40K)是通过使用屏蔽的高计数效率NaI(Tl)系统从不同的伊拉克当地市场收集的装饰材料中测量的。计算了所有样品的辐射危害指数。结果表明，238U、232Th和40K的比活度在装饰石材中最大，在装饰雪花石膏中最小。本研究的结论是，大多数装饰材料样品的天然放射性和辐射危害均在联合国原子辐射影响科学委员会(UNSCEAR)、国际放射防护委员会(ICRP)、经济合作与发展组织(OECD)等国际报告的允许范围内。因此，根据辐射范围，本研究中大部分装饰材料样品都可以在无健康风险的情况下使用。
