摘 要:建筑材料中的氡-222、镭-226、钍-232、钾-40等天然放射性核素衰变产生的射线对人体健康产生极大危害,为了解广东省的建筑材料放射性状况,为广东省建筑材料市场的天然放射性水平检测提供基础依据,本文针对广东建材市场现状调查,设计了广东省建筑材料及不同类型建筑物放射性调查方案。方案中设计通过对广东省广州、珠海、深圳、韶关及佛山五个城市中工厂、酒店、住宅、医院、学校(幼儿园)、古建筑、广场、商场等不同类型建筑物的室内放射性进行调查,并对同一居民楼中使用不同建筑材料的居民室内进行放射性调查,得出广东省的室内的放射性水平以及高水平的放射性建材种类;通过对佛山、云浮、潮州、深圳、东莞以及珠海六个建材产业较为发达地区的建材市场中不同建筑材料(瓷砖、陶瓷、大理石、花岗石、水泥、石粉、实心砖、空心砖)及装饰材料的放射性调查分析,得出广东省建筑材料的放射性水平,以及高放射性的建材种类。Since the rays frorm the decaying of natural radionuclide such as 222R n , 226R a , 232T h and 40K in building materials are very harmful to h u m a n health, in order to k n o w the radioactive status ofbuilding materials and provide data support for carrying out natural radioactive level detection of building materials markets in G u a n g d o n g Province, this paper presents the results from an initial in-vestigation on building materials markets in G u a n g d o n g and a survey plan designed specifically for in-vestigating radioactivity of different types of buildings and building materials. In order to k n o w indoor radioactive level in general and indoor building material types with high radioactive types of buildings such as factory , hotel , dwelling , hospital , school (kindergartening , square and market in five cities including Guangzhou , Zhuhai , Shenzhen , Shaoguan and Foshan in Guangdong Province are included in survey plan for investigating the indoor radioactive status ingeneral , and the indoor radioactive status of household using different building materials within thesame building. At the same time , in order to k n o w the radioactive level in general for building mate-rials in Guangdong Province and building material types with high radioactive level , different types of building materials such as tile , ceramic , marble, ganite , cement , rock flour , solid brick and air brick and decorative materials in six cities including Foshan, Y u n f u, Chaozand Zhuhai in Guangdong Province are included in survey plan for investigating the radioactive status.
