建筑材料表面析出氡的监测方法研究

目的 研究建筑装饰材料(简称建材)表面析出氡的监测方法，主要是为人们安全使用建材提供依据。方法 为了解常见建材表面的氡析出水平，采用自行研制的静电收集装置及驻极体收集装置。依不同环境及现场条件，对24间工作用房、1个演播厅及1个计算机房实施联合监测。结果 利用这两种装置配合使用的综合测量方法，可以得出满意的监测结果。结论 这种联合监测方法适用于现场的常规监测，其监测结果还可为室内场所环境的放射性危害分析、所采取的相应防治措施以及氡水平评价等服务。

Study on a Monitoring Method for Radon Emitted from Building Material

Objective To develop a monitoring method for radon emitted from building and decoration material to provide criteria for its safe use.Methods Self developed electrostatic collector and electret collecting device were used.Results The integrated measuring method was applied coordinately according to different environment and on site condition to get promising results.It has been used successfully in 24 office rooms,1 performance studio and 1 computer room.Conclusions This method is feasible to be used at on site routine monitoring.The results obtained could be used in indoor radiation pollution analysis,by which the dosage of radon could be evaluated and appropriate measures could be taken.
