ULTRAVIOLET AND LASER-RADIATION SAFETY

Both ultraviolet radiation and laser radiation occupy part of the spec trum designated 'optical radiation'. Thus, measurement techniques are similar and the same organs (eyes and skin) are at risk from accidenta l exposure. However, the equipment used to produce ultraviolet and las er radiation differs substantially and the harm caused by each type of radiation is also different. Another significant difference arises fr om the fact that ultraviolet radiation is natural with associated gene ral population exposure. Consequently, the present article reviews the current status of both ultraviolet and laser radiation with the mater ial divided into two sections where each hazard is considered separate ly.
