ANALYTICAL STUDIES OF THE EFFECT OF MICROWAVE RADIATION ON THE BEHAVIOR OF SOME ELEMENTS IN SOMERAT ORGANS

Abstract

In this Work four groups of adult albino rats were used; the first group as control, the second group was exposed to microwave radiation I 'h hours/day for seven consecutive days, at a dose of 15 mW/cm2 and frequency 10.525 GHz. The third was exposed like the second, but for 24 consecutive days, while the fourth was treated as the third and then left for two weeks as a rest period. Then animals were sacrificed and the blood, brain, heart, kidney and liver levels of some major and trace elements (calcium, iron, manganese, copper, nickel, zinc, selenium and molybdenum) were estimated by the energy dispersive X-ray fluorescence technique (EDXF); as an easy, rapid, multi­ elemental and need low weight of samples

Calcium, iron and manganese showed a significant increase in the exposed groups, while zinc, copper and molybdenum showed a significant decrease when compared to control. Nickel showed a significant drop in the acute and chronic exposure groups and restored its normal figure in the chronic exposure then rest group, but it was undetectable in the brain for all groups.

As for selenium it showed a significant drop in both acute and chronic exposure groups and a significant rise in the chronic then rest group in the blood. But in brain it was undetectable for the control and chronic exposure groups, while a significant rise in the others. These changes were explained by the microwave variant effects on ion fluxes via, the effect on the ion channel properties of cell membrane, interaction between the cellular membrane molecules containing these ions, voltage changes across the cell membrane.

The changes were highly prominent in the acute exposure and less in the chronic exposure one and least in the chronic then rest group, this seemed to . / follow the same pattern of stress exposure phenomenon. The changes could be related to many side effect and toxic microwave effect, especially those of mental and neurological manifestations as fatigue, headache, memory affection. It is here recommended to give more interest for the protective and isolating devices, decrease periods of exposure, routine check up, of this elements levels give supplementary and/or chelating therapy to the disturbed ions, as well as to do more research works.
