## 3 Results and Discussion
Similarly, Figure 4 shows that the electric field level variation is based on the various scenarios that are described in Table 3 and the values obtained from Table 7.  
Repeated measurements resulted in average electric field levels that differed from each other by about \(\pm\)11%. Nonetheless, we observed that the effect for crew members and passengers from marine vessel transmitters is minimised from the measurements that were carried out under 11 different scenarios and at 12 different locations on the vessel. Our results demonstrated that the electric field levels measured complied with the international (ICNIRP) [1] and the Australian (ARPANSA) standards [4] and were also compatible with the measurements recorded in a previous study [9]. Nevertheless, for the ICNIRP limit, the acute effects are determined by the intensity of the radiation, and cumulative effects were not presumed, as also indicated in our previous research [14]. For low frequencies, a limit of the magnetic field could be exceeded even if the electric field limit is low. In contrast to this, at high frequencies (\(>\)100 KHz), magnetic and electric fields are decoupled when the near-field is considered. \begin{table}
