一例居室内装饰材料负离子免漆板的辐射水平评价与相关监管建议

Evaluation of radiation level of negative ion paint-free panel for indoor decoration and relevant suggestions on radiation supervision

目的对含放射性物质的室内装饰材料负离子免漆板的放射性水平进行测量与评价,对发现的问题探讨解决的办法与对策。方法依据国家标准对材料的放射性比活度以及室内环境γ剂量率进行监测与分析。结果该负离子免漆板所含放射性符合GB 6566-2010中A类装修材料的技术指标要求,但其造成的室内环境辐射水平和对用户造成的个人附加剂量有明显增加。结论低剂量辐射对个人心理健康影响不可忽视,需加强对含放射性物质产品的监管,慎重评价与判断产品的正当性。

Objective To measure and evaluate the radioactivity level of negative ion paint-free panel for indoor decorative materials containing radioactive substances, to find out the problems, and to explore the solutions and countermeasures.Methods The specific activity and gamma dose rate of indoor environment were monitored and analyzed according to national standards.Results The radioactivity of the negative ion paint-free panel met the requirements of Class A decoration materials in GB 6566-2010. But the radiation level of indoor environment caused by the negative ion paint-free panel and the personal additional dose to users significantly increased.Conclusion As the influence of low dose radiation on personal mental health can not be ignored, it is necessary to strengthen the supervision of products containing radioactive substances, carefully evaluate and judge the justification of products.
