Laser products today have entered just about every area of the human environment. Laser products are used in medical treatment and diagnosis; in the home in entertainment products; in industry for material processing, process control, metrology and inspection; in communications; in the military in construction and agriculture for surveying and alignment; in physical, chemical and biological research; and in environ-mental protection and pollution control. The outstanding property of the laser that makes it so useful in so many applications, radiance, introduces a potential for exposure hazards that is somewhat unique. Because of the diversity of applications and hazard potential, the Bureau of Radiological Health, FDA, enacted a performance standard for laser products under the Radiation Control for Health and Safety Act of 1968. The following discussion will address the structure and requirements of the act and standard, and the organization and function of the agency in enforcement activities.
