Exogenous radiofrequency electromagnetic exposure of outdoor workers who are managing touristic boat journeys

The frequency pattern of radiofrequency electromagnetic field exposure of outdoor workers, who are managing touristic boat journeys, has been investigated using frequency-selective portable, autonomous, data-loggers which allow recognizing the time pattern of exposure level and the composition of its sources.Significantly different patterns of relative contributions to recorded workers' exposure from various sources were found during activities at pier (dominating base stations downlink components of exposure) and during the touristic journey by boats (dominating mobile terminals uplink components, with exposure contribution also from radio and television terrestrial emitters).The differences found in the workers' exposure pattern recorded in particular microenvironments need attention when considering the protection measures aimed at improving the electromagnetic environment there.
