摘　　要：紫外杀菌消毒效果和辐射安全是一枚硬币的两面,紫外消杀决不能简单套用传统照明技术,而对紫外辐射量值客观准确的测量,能够指导产品研发设计,检验产品是否符合需求,推进紫外杀菌产品在各场景中的应用。基于紫外杀菌消毒原理,分析了表面消毒和空气消毒中所需计量测试的辐射度参数,提出了有效辐射度的概念,并提出需要根据实际应用测量和评价紫外辐射产品的辐射空间分布;对于安全防护,结合有关标准分析了辐射危害加权量的测量方法,考虑到可能存在的防护措施失效,还应测量计算出杀菌产品的安全距离。进一步,探讨了紫外辐射测量的关键技术,特别针对紫外杀菌产品的辐射分布测量提出了解决方案。Ultraviolet(UV)disinfection effect and radiation safety are two sides of the same coin,so the evaluation method for traditional lighting can not be simply applied to UV disinfection,and the objective and accurate measurement of UV radiation can guide product development and design,quality inspection and application promotion.Based on the principle of UV disinfection,the paper analyzes the radiation parameters needed for measurement and evaluation in air&surface disinfection,puts forward the concept of effective radiation and the need to measure and evaluate the spatial radiation distribution of UV radiation products according to the actual application.For UV protection,the measurement method of radiation hazard weighted quantities combined with relevant standards are also analyzed.In addition,considering the possible failure of protective measures,the safe distance using UV germicidal products should be measured and calculated to ensure personal safety.Furthermore,the paper discusses the key measurement technology of UV radiation,especially for the radiation distribution measurement of UV germicidal products.
