"exposure limit value" means the limits on exposure to optical radiation which are based directly on established health effects and biological considerations. Compliance with these limits will ensure that workers exposed to artificial sources of optical radiation are protected against all known adverse health effects;
"irradiance (E) or power density" means the radiant power incident per unit area upon a surface expressed in watts per square metre (W m-2);
"laser (light amplification by stimulated emission of radiation)" means any device which can be made to produce or amplify electromagnetic radiation in the optical radiation wavelength range primarily by the process of controlled stimulated emission;
"laser radiation" means optical radiation from a laser;
"level" means the combination of irradiance, radiant exposure and radiance to which
