IMPACT OF HOUSEHOLD MICROWAVE OVEN NON-IONIZING RADIATION ON BLOOD PLASMA CORTISOL LEVELS IN RATS AND THEIR BEHAVIOR.

In medical literature is known that the electromagnetic waves own a harmful effect on human organism. Is convinced shows that surround household microwave oven exist certain quantity of non-ionizing radiation leak. The aim of the present work is study the effect of non-ionizing radiation, emitted by household microwave oven, on the body weight, emotional and locomotor activity and cortisol blood plasma level in rats. 6 weeks Wistar rats cage were placed near microwaves oven, from closed door escape 727,24±84,55 Mw/m² Power Density microwaves. The oven was switch over two times a day for 3-3 minutes during 10 days. Experimental and control group rats are weighed before and after experiment. To assess the emotional state and locomotor activity open field test was performed and for determine stress level the concentration of plasma cortisol was measured. It was found that after 10 days, in microwave radiation exposure group rat body weight gain increase more than in control group. In open field test, microwave radiation exposure group rats spent more time in center square than control group rats, line crossings, center square entries, stretch attend postures are also more in microwave radiation exposure group rats than in control. Cortisol level in plasma were increased in microwave radiation exposure group rats than in control group. Complete analysis of our results have convinced shown the necessary to study of household microwave oven non-ionizing radiation.
