Exposure levels are examined in and around several types of vehicles equipped with mobile communications equipment. Additionally, exposure levels are observed near the head of an individual operating a hand-held walkie-talkie. Measurements of energy densities inside vehicles indicate highest exposures occur near the head and near the driver's hands (when on the steering wheel). Outside the vehicles, highest exposure levels occur near sharp edges and corners, wheel wells, and certain protuberances. Exposure levels are greatly influenced by location of the antenna and degree of metallic shielding. Highest exposure levels occur near the operator's eye for a hand-held walkie talkie.
