The Sun and Ultraviolet Radiation,ous sources used in industry. The energy conveyed by this radiation on the one hand and its absorption by certain molecules of living beings on the other hand triggers important reactions, particularly at the level of the gene pool of the exposed cells. The consequences of these reactions in the sho
