[Experimental study of the effects of acute uneven microwave irradiation]

The purpose of the study was to reveal parts of the body affected by radiation most of all in uneven microwave irradiation (current frequency of 2.4 GHz/s) by the destruction criterion taking account of some indicators of the absorbed power of electromagnetic radiation (EMR). Uneven irradiation was achieved by the screening of some parts of the body with radiopaque material leaving unshielded parts subjected to irradiation. Control over the redistribution of absorbed energy was exercised by means of multichamber phantoms. In experiments on animals (female rats) within the range of specific absorbed power of 15-40 mWg the utmost affection of the cranial segment was revealed. The results show good correlation with a curve of the effect of 50% destruction criterion in total EMR irradiation.
