Assessing personal exposures to environmental radiofrequency electromagnetic fields

摘要

Recent advances in the capability of body-worn instruments for measuring the strengths of environmental radiofrequency signals have opened up a range of exciting new research possibilities. The readings from these instruments can be used in health related studies, but they have to be considered carefully when developing exposure metrics, as does the physical dosimetry concerning interactions between radio waves and the body. Several studies have distributed the instruments to large groups of people and analysed the gathered data in relation to possible determinants of exposure. This article reviews the state of the art in personal exposure measurements at radiofrequencies.
