USING NEW TECHNOLOGICAL METHODS IN DEFINING SAFE RANGES FOR ELECTROMAGNETIC RADIATIONS IN BUILT ENVIRONMENT

Abstract

This study aims to determine the safe range of exposure to the electromagnetic fields surrounding the human being. This objective requires studying and determining the environmental and health impacts resulting from exposure to the most dangerous sources of electromagnetic fields which are medium voltage transformers present in various residential, service and commercial areas. The results will help decision-makers in proposing solutions that lead to reducing health effects In this study our goal is to prevent all health and environmental effects of electromagnetic fields created by medium voltage transformers. The following steps are the major steps to achieve our goal: 1. Definition of electromagnetic fields, their properties and sources, especially medium voltage sources, and the use of previous studies in that field. It is worth noting that previous studies in this field were not available in the same quantity of studies of high voltage sources or radio paths (mobile phone). 2. Study the effect of electromagnetic fields of various frequencies on the environment and public health in general. Also, measure the health and environmental effects of fields around medium voltage transformers and also introduce international standards for exposure to these fields. To achieve this, an EMF Magnetometer was used to obtain several measurements varied depending on the loads loaded on these transformers. 3. While performing the measurements, it was noticed that there was a decrease in the values of the measurements around the transformers in the rooms which had doors made with tin. The measurements were repeated in some locations using the galvanized tin sheet thickness of 1 mm at the available distances in the different rooms. A comparison was made between the original measurements and the measurements made using
