Main mechanisms of interaction between weak magnetic fields and biological objects are considered in the article. This interaction is analyzed on the basis of the role of cryptochrome-depended mechanisms of the influence of magnetic field upon cell’s genome, which have been discovered last time. The principal possibility on the genes-depended regulatory influences of both weak magnetic fields and electromagnetic irradiation of low intensity upon chronorhythms of organisms with different level of organization have been critically investigated. The main priority statements which are postulated by authors of the theory, and which are based on research data are attracted for the discussion. Hence, physical epidemiology as a new fundamental and innovative direction of science development is stressed.
