EMF exposure assessment in proximity to metallic parapets

This paper presents RF-EMF exposure assessment carried out in an observatory recently opened for general public visitation, where there are many RF sources in the surrounding area. Some points of interest have exceeded the ICNIRP exposure limits for the general public and, to accomplish with normative limits in the far field region, relevant stations reduced radiated power. Nevertheless, the total electric field strength in the vicinity of the Observatory's metallic parapet still numerically overcomes normative limits in the near-field region due to re-radiation. Thus, discussion about the effective influence on RF-EMF measurements and possible errors introduced when the evaluation is carried out close to metallic objects as well as re-radiation analysis using numerical simulation are presented.
