New methodic approach to hygienic evaluation of electromagnetic energy absorption in near-field zone of irradiation source

Abstract

Nowadays, essential objective of hygienic evaluation of electromagnetic energy absorption of mobile radio-frequency devices is specification of new approach with consideration of russian and international regulation principles. This approach enables to ealuate correctly users' actual exposure conditions and consider energy absorption by human in near-field zone of the irradiation source. The work is aimed to study applicability of hypothesis on possible relations between magnetic part of electromagnetic field and specific absorbed capacity. This hypothesis is considered a basis for designing a new methodic approach to hygienic evaluation of individual mobile communication devices in near-field zone of the source. Analysis of the data obtained demonstrates that visible difference between suggested and classic methods decreases with higher frequency. Every studied source in its near-field zone can be characterized by optimal conditions for the suggested method usage with error less than 2 dB. The study results on relations between decreasing electromagnetic energy and specific absorbed capacity value make possible further improvement of methods controlling electromagnetic field levels in assessment of personal mobile radio communication devices.
