Variability of Radiosensitivity Manifestation to Chronic Influence of Electromagnetic Fields Impulses

Abstract

In numerous researches confirmation of morphofunctional changes divergence of a jejunum mucous membrane indicators is found at influence of electromagnetic fields, shown jet processes and adaptation reactions, depending on parameters of the influencing radiation sources: impulses frequency, intensity and duration of influence which combination reveals various consequences of the irradiated biological object [1, 2, 5]. In the experiment executed on white laboratory rats males with initial age 4 months studied dynamics of the morphoenzymological indicators sensitivity degree of a jejunum mucous membrane after 5, 7 and 10 months of electromagnetic fields impulses influence, with density of the induced currents in a body of rats 0.37, 0.7, 0.8, 2.7 kA/ m² and frequency of impulses 50, 100 and 500 in a week irrespective of their divisibility lasting 15÷40 ns. The carried-out complex analysis of biotropic effect formation variability of the electromagnetic fields impulses parameters in radio sensitivity of morphological equivalents of a jejunum mucous membrane functional condition, her morphoenzymological indicators allowed to reveal selective sensitivity, taking part in the regulation of a tissue homeostasis defining activity of transport processes and also to assume realization "time effect", the chronic radiation allowing to estimate risk from all influencing electromagnetic fields impulses parameters.
