[Assessment of exposure of workers to artificial optic radiations].
EC Directive 2006/25/EC, recently receipted by Italy, requires the evaluation of workers exposition to optical artificial radiation, both coherent (LASER) and incoherent. Evaluation criteria based upon International Commission on Non Ionizing Radiation Protection (ICNIRP) guidelines require for incoeherent sources an evaluation depending on radiation spectrum. Starting from measurements techniques and results, some situations requiring a focusing in evaluation are outlined. Waiting for needed clarifications from prevention authorities, some considerations useful in performing an evaluation without measurements are shown. UV-visible sources require a knowledge of spectrum, measured or certified by the manufacturer. The exposition to optical radiation generated by heated material can be evaluated by integrated measures knowing black body radiation spectrum.
