The ways and effects of ultraviolet radiation on the human and animal body

Abstract

The rapid technical development of human society on Earth leads to the pollution of its atmosphere and an increase in the optical radiation of the Sun and its main part — light and ultraviolet radiation. In order to properly protect and control the effects of optical radiation on the human body, it is necessary to know and understand the process of absorption and conversion of optical radiation falling on the surface of the body. The material contains the original results of experimental studies optical radiation transmission through a sample of quasi-vital skin with pigs of different ages. The reliable results of the percentage ratio of the amount of optical radiation of the optical spectrum that passes under the skin through the skin layer and the individual one wool depending on the species and age of the animal are obtained. The results of the experiment showed that the optical radiation of the Sun affects the body of the animal through the skin, as well as inside the cylinders of a separate wool. This new knowledge is important to monitor and control optical radiation for young and old animals with different wools. A new approach has also been proposed for the dosing method of ultraviolet radiation in accordance with the body's needs for vitamin D.
