ABSTRACT

The dosimetric concept of measurements of electromagnetic radiations (EMR) during irradiation of biological objects can be realized by methods of mathematical modelling of EMR interactions with biological objects, which can be represented as an image of the human body as a uniform ellipsoid of revolution. The efficient surface of EMR absorption for the models shows a marked resonance dependence on the radiation frequency. The ratio of the largest to the smallest axes of the ellipsoid of revolution can be used as a resonance criterion. Besides, radiation polarization needs to be taken into consideration. This paper discusses the frequency dependence of the efficient absorption surface for three major types of radiation polarization. The paper demonstrates an applicability of the calculation method to the evaluation of the EMR absorbed dose rate.
