The results of measurements and calculations of microwave radiation power density produced by two typical traffic radar systems were reported and discussed in this report. Traffic radar systems are small portable units used by police to determine speed of vehicles relative to that of the police vehicle in which the unit is mounted. It was determined that traffic radars were low-powered devices, incapable of producing environmental levels of microwave radiation greater than 0.01 W/sq m at distances where persons would normally be exposed during use of such systems. Police personnel using the radar system could be exposed to power densities up to 36 W/sq m. For comparison purposes, the threshold for exposure allowed by the OSHA occupational exposure standard is 100 W/sq m for exposure durations of 6 minutes or more.
