PROBLEMS OF HYGIENIC REGULATION OF LASER RADIATION FOR POPULATION IN RUSSIAN FEDERATION. REVIEW

Hygienic studies have shown that the laser radiation of projectors can exceed Maximum Allowable Levels (MAL). Exposure to laser radiation levels not exceeding MAL induced unpleasant sensations in the eyes, temporary color perception disturbances, temporary blindness, headache in show participants. Specificity of laser radiation and the peculiarities of its regulation do not allow it to fit into the framework of exclusively numerical values that are established in the current regulatory document, therefore it is necessary to create a separate document on laser radiation that would contain, in addition to the MAL, requirements for laser safety. The determination of the Maximum Allowable Levels assumes the absence of hidden and temporarily compensated changes, however, MAL standards were initially calculated based on the damaging effect of laser radiation and did not take into account short-term changes. It is proposed to revise the MAL standards for population based on the reversible effects of radiation, such as temporary blinding.
