Comments on the 2013 ICNIRP Laser Guidelines

摘要： IN 2013, the International Commission on Non-Ionizing Radiation Protection (ICNIRP) published guidelines on exposure limits for laser radiation of wavelengths between 180 nm and 1,000 mm (ICNIRP 2013a). Since then, the application of the limits has shown that some additional guidance is needed for complex exposure cases. This statement refers primarily to extended laser sources as opposed to the more common point sources. Questions received about the application of exposure limits for retinal thermal hazards from extended sources subtending more than 5 mrad made it clear that clarifications were needed regarding the description of angular subtense and repetitive-pulse correction factors. It is also confirmed that the exposure limit to protect the cornea in the far infrared wavelength range is not based on aversion responses. Also, this statement provides clarification on symbols used in the tables.
