Use of portable exposimeters to monitor radiofrequency electromagnetic field exposure in the everyday environment

Spatial and temporal distribution of radiofrequency electromagnetic field (RF-EMF) levels in the environment is highly heterogeneous. It is thus not entirely clear how to monitor RF-EMF exposure levels in the environment in a representative and efficient manner. In a microenvironmental survey a trained person uses portable measurement devices to conduct numerous RF-EMF measurements within a short time at different locations within various microenvironments such as residential areas, city centers and public transports. The aim of this study was to evaluate the appropriateness of such a microenvironmental survey for the purpose of a RF-EMF monitoring. Thus, the aim of the study was to evaluate the reproducibility and spatial representativity of such measurements.
