The International Non-ionizing Radiation Committee (INIRC) of the International Radiation Protection Association (IRPA) first published Guidelines on Limits of Exposure to Laser Radiation in 1985 [1]. Since that time, as a result of an expanded laser database, the Guidelines were revised in 1988 [2]. Prior to presenting the guidelines on laser exposure, it is worthwhile to explain the process by which IRPA/INIRC develops guidelines on non-ionizing radiation (NIR).
