Abstract Portable transceivers emitting in the UHF radiofrequency band are sources of human electromagnetic exposure, when located in front of the face. Three output power levels were tested while the exposed target was a phantom filled with dielectric liquid simulating average human head behavior at the used frequency of 446 MHz. A flat phantom and a head phantom were scanned by an automatic E-field probe robot, based on the standardized procedure, in order to report specific absorption rates of energy deposition in the head. A discussion on the obtained results is provided, together with a comparison with other similar results in the literature. Consequences upon the safe use of such devices by public or by occupational personnel in the proximity of the brain and eyes are underlined.
