Abstract

The reliable evaluation of electric and magnetic field exposures with relevant radiofrequency exposure limit standards is important in order to provide protection against known adverse health effects. The evaluation of human exposure levels to radiofrequency, electric and magnetic fields and power density is required for assessment of compliance with technical standards, and it can be conducted by either measurement or numerical calculation. This paper presents a comparison between different computational tools (ProX5 EME, Cylindrical wave model, Flat-zone method and NEC as a reference) for the analysis of zone boundaries for human exposure to radiation from a Yagi-Uda antenna, operating at 450MHz with a maximum power of 50W. The results are based on the guidelines for limiting exposure to time-varying electric, magnetic and electromagnetic fields, created by the International Commission on Non-Ionizing Radiation Protection (ICNIRP).
