摘要 激光产品的光辐射安全评价对相关人员采取合适的防护措施具有重要的意义。基于简单测量方法可能会低估激光产品光辐射危险的情况,本文阐述了表观光源及其对向角在激光产品分类中的意义,并通过实例对简单测量方法和扩展源方法做出对比。结果表明选择合适的方法检测对人体最不利的辐射,才能得到准确的分类,进而对激光产品的辐射危险做出评价。 Radiation safety evaluation of laser products is of great significancein adopting appropriate protective measuresfor correlative personnel.Based on the situationthat the simple measurement method may underestimate the radiation risk of laser products,the significance of the apparent source and angular subtense used inthe process of classification of laser products is elaborated in the article,and the comparison is made between simple measurement method and expand sourcemethod by example.The result indicates that the measurement radiation energy of most unfavorable circumstance of human bodywith suitable measurementmethod can acquire accurate classification,making evaluation for radiation hazard of laser products.At last,maximum permissible exposure and nominal ocularhazard distance for evaluation parameter of laser radiation safety are introduced and illustrated in the article.
