Abstract
Interaction of electromagnetic radiation (EMR) from the optical range of biologic objects as shown in the wave, and quantum effects in the probability of formation of which varies depending on the wavelength. In assessing the effectiveness of EMR in the optical range, along with such laws of its wave propagation, as a reflection, scattering and absorption, it is also necessary to take into account the effects of corpuscular photochemical, photoelectric, photolytic and others. Photobiological basis of the mechanism of action of EMR optical range is the energy absorption of light quanta (photons) by atoms and molecules of biological structures (law Grotgus-Draper), which resulted in the formation of electronically excited states of these molecules with the transfer of photon energy (internal photo effect). This is accompanied by electrolytic dissociation and ionization of biological molecules. The degree of manifestation of photo biological effects in the body depends on the intensity of the optical radiation, which is inversely proportional to the square of the distance from the source to the irradiated surface. Accordingly, in practice, determine not the intensity and irradiation dose at a certain distance from the source of exposure by the exposure time.
