Analysis of Photobiological Processes and Indicators of Photobiological Safety of Radiation Source of Light

Abstract

Annotation -It was established that photobiological processes that arise under the influence of optical radiation cause photochemical and thermal reactions in organisms. Such reactions are directly related to the absorption of light from natural and artificial sources of radiation. It is established that the depth of penetration of optical radiation depends on the wavelength. Radiation of "blue light" is the most dangerous for the harmful effect on the retina and affects melanopsin cells. Also, in the visible area of the spectrum of artificial light sources, which are used for a long time in the evening and night periods, there can be dangerous "green light" as it is able to break the circadian rhythm and create a hormonal imbalance. Thus, the prolonged action of ultraviolet, visible and infrared radiation on the eyes and skin can cause a gene mutation, burns, disease and changes in the circadian rhythm. The article analyzes and systematizes the possible consequences and damage that may result from such an effect of optical radiation.
