编者按:光辐射危害不管是在环境照明还是医疗器械中,都越来越引起人们的严重关注,也成为含光源医疗器械质量评价的重难点。国际、国家、行业标准中,都逐步开始要求进行光辐射危害评估。光辐射危害反映了光源与人体的生物学效应,一方面与光源的性质如激光/非相干光、紫外/可见/红外、发散/聚焦、照射时间方式等有关;另一方面又与人体特性如
Editor’s Note: The dangers of light radiation Whether in environmental lighting or medical devices, are causing more and more serious concern, but also become a light source medical device quality evaluation of the heavy difficulty. International, national and industry standards, are gradually beginning to require light radiation hazard assessment. Light radiation hazard reflects the biological effects of the light source and the human body, on the one hand and the nature of the light source such as laser / incoherent light, UV / visible / infrared, divergence / focus, exposure time on the other hand, and human characteristics such as
