Electromagnetic fields: risk perception and acceptance

Abstract

Introduction and Aims – Electromagnetic fields are found naturally in the universe. Some years ago, the levels relating to electromagnetic fields were relatively stable. With technological development, exposure to new sources of electromagnetic radiation has increased. It is to be expected, then, that public concerns, primarily about the potential health risks derived from electromagnetic fields, have also increased. The aim of this study was to discover and analyse individual people’s concerns about and understanding of electromagnetic radiation, based on the fact that one of the main factors for adopting precautionary measures is how risk is perceived by the individual person. Methods – This is a descriptive quantitative study. The sample is composed of 320 individuals and is a non-probability, convenience sample. Results – It was found that the respondents are “not very concerned” about exposure to electromagnetic fields, have relatively little knowledge about sources of electromagnetic radiation in their everyday life and do not take precautions about exposure to electromagnetic fields. Conclusions – Individuals showed an immature awareness of the issue of electromagnetic radiation, partly justified bythe absence of sensory mechanisms that are able to detect it. Investing in education and raising awareness could guarantee a future that has better quality of life. It is important for several bodies to join forces (health care, media, and education). Schools, through children and young people, are an excellent means for transmitting information
