As for the skin over the whole body (Figure 4), the greatest pSAR\({}_{10g}\) was found in CONF1 and was equal to 6.619 mW/kg (mean = 0.221 mW/kg; median = 0.029 mW/kg) and 6.818 mW/kg (mean = 0.122 mW/kg; median = 0.005 mW/kg) for the frontal and lateral orientations, respectively; the pSAR\({}_{10g}\) in the other configurations was 84-98% lower than that in  
Figure 6: SAR\({}_{10g}\) (left \(y\)-axis, box plot) and pSAR\({}_{10g}\) (right \(y\)-axis, square symbols) in the brain tissue for the five different examined configurations, considering the frontal and orthogonal orientations of the Ella model. The center line in the boxes is the median; the bottom and top edges are the 25 th and 75 th percentiles. The lower whisker extends to the minimum value, while the upper whisker extends to 1.5 times the height of the box. Figure 7: SAR\({}_{10g}\) (left \(y\)-axis, box plot) and pSAR\({}_{10g}\) (right \(y\)-axis, square symbols) in the eye tissues for the five different examined configurations, considering the frontal and orthogonal orientations of the Ella model. The center line in the boxes is the median; the bottom and top edges are the 25 th and 75 th percentiles. The lower whisker extends to the minimum value, while the upper whisker extends to 1.5 times the height of the box. CONF1, ranging from 0.061 mW/kg (mean = 0.004 mW/kg; median = 0.001 mW/kg) in CONF4 in the orthogonal orientation to 0.675 mW/kg (mean = 0.037 mW/kg; median = 0.002 mW/kg) in CONF5 in the frontal orientation. In Figure 5, the same analysis is reported for the skin tissue of only the head. We noticed that the pSAR\({}_{10g}\) value in the skin of the head was the same as that observed for the skin over the whole body (Figure 4) in all configurations but in CONF 2 in the frontal orientation and CONF 4 in the orthogonal orientation, where the pSAR\({}_{10g}\) over the skin of the whole body (Figure 4) was higher than at the head. As a matter of fact, in these latter two configurations, the maximum of SAR\({}_{10g}\) in the skin of the whole body was localized at the arm, because this was the body part closer to the 5G-V2X antennas. In Figure 6, the analysis is focused on the whole brain, another critical and important region for assessing human exposure levels. As expected, the exposure levels in the brain are lower with respect to the skin in all configurations due to the low penetration of the field radiated by the two 5G-V2X antennas working in the GHz region. The reduction of pSAR\({}_{10g}\) with respect to the skin ranged from 23% to 92%, depending on the configuration. The distribution of SAR\({}_{10g}\) in the brain exhibited the same trend observed in the skin of the whole body and of the head, that is, the highest exposure was observed in CONF 1. Namely, the pSAR\({}_{10g}\) value in CONF 1 is equal to 3.038 mW/kg (mean = 0.066 mW/kg; median = 0.013 mW/kg) for the frontal orientation and 2.716 mW/kg (mean = 0.080 mW/kg; median = 0.002 mW/kg) for the orthogonal one, whereas in the other configurations. the pSAR10g value was 84-99% lower than that in CONF 1. Lastly, in Figure 7, we analyzed the SAR\({}_{10g}\) distributions obtained for the eyes. Also for the eyes, the highest exposure levels are obtained in CONF 1 in the frontal orientation, as the antenna beam is more directed to the eyes area than in the orthogonal orientation. The pSAR\({}_{10g}\) value in CONF 1 is equal to 3.765 mW/kg (mean = 2.280 mW/kg; median = 2.212 mW/kg) for the frontal orientation and 1.845 mW/kg (mean = 0.488 mW/kg; median = 0.103 mW/kg) for the orthogonal one. For the orthogonal orientation, in all the examined configurations, only one eye is much more illuminated by the radiation field of the 5G-V2X antennas, resulting in almost null values of exposure for the eye further away. Tables 1-4 list the QCD and the percentage of values higher than 0.7 pSAR\({}_{10g}\) for the examined tissues.
