• Abstract:
  The objective of this project was to measure the microwave radiation emitted by speed measuring radar units to obtain a data base for evaluating the potential radiation hazards of these devices. Measurements were taken both in free-space and with the radar units mounted in typical operating positions inside or attached to a four-door sedan. The free-space measurements were made at four different distances to determine the field strength as a function of distance from the radar units. Calibrated radiation level probes were used to measure the field strength inside the automobile and scan the interior volume of the four-door sedan with particular attention to the driver and passenger locations. Twenty-two radar units were involved, and the data are presented in a power density format. /Abstract from report summary page/
