title: Assessment of exposure to mobile telecommunication electromagnetic fields.
abstract: Typical general public exposures around mobile radio service base stations consume only tiny fractions of exposure levels. Maximal immissions at maximal transmit power of base stations amount to several percent of power density reference levels; typical immission levels are about one tenth of a percent or even less. The distance to base stations is no reliable exposure classifier. More important are the orientation relative to the main lobe of the station and sight conditions from measurement point to the base station. Mobile phones cause higher exposures to the user than base stations. At maximal transmit power up to 80 percent of the basic restrictions are consumed. Therefore, actions to minimize exposure to mobile phones, e.g. by using a headset, have a larger potential than shielding against emissions from base stations. Both base stations and mobile phones apply power control mechanisms, capable to significantly reducing the transmit power and the associated exposure depending on the communication traffic. Present research investigates, whether children are more exposed to mobile telecommunication systems than adults.
