An Analysis of the Spatial-Temporal Variability of the Near Field Components in the Proximity of a TETRA Portable Terminal

The paper is focused on the electromagnetic exposure assessment in the proximity of a Terrestrial Trunked Radio (TETRA) terminal. For the first time distinct measurements of the electric field component (E) and of the magnetic field component (H) are presented in the distance range 8-20 cm. The results show that the E-field component has a greater prevalence on the exposure. Maximum values of 100% for E, and 17% for H component respectively were encountered in the near field of the terminal, if compared to the occupational limits given in the ICNIRP protective guidelines.
