摘要

A radiofrequency (RF) electromagnetic radiation safety assessment had been carried out at public access points within the compound of a teaching hospital. The frequency band investigated ranged from 87.5 MHz to 2.6 GHz. Eighty-eight measurements were made using a spectrum analyser coupled with a log-periodic antenna. The objective was to determine the level and nature of RF fields within the immediate premise of the facility where patients of health conditions are kept and treated. Results complied with the International Commission of Non-Ionising Radiation (ICNIRP) guidelines. The values of the resolved electric field at four spatial heights ranged from 1.00 +/- 0.144 mV/m to 1.174 +/- 0.169 V/m. Power densities varied from 2.65 +/- 0.38 nWm(-2) to 3.66 +/- 0.528 mWm(-2). There were relatively high contributions from frequencies above 900 MHz compared with contributions from lower frequency bands.
