# Assessment of Electromagnetic Exposure to a Child and a
## 6 Discussion
The Tmax pattern closely aligns with the SAR10g surface pattern, showing similar influences from electromagnetic reflections. Distinctively, the presence of the elevator notably alters the electromagnetic absorption rate and temperature distribution patterns. From the results obtained of the dosimetry study, the graphic distributions of specific absorption rate over 10 g for fetus and Pregnant II have a similar pattern. The highest EM power density over 10 g and highest temperature values across all scenarios taken, for both the pregnant model and the fetus are recorded at configuration 2 with the phone in a tilt position, emphasizing that positioning is the primary factor influencing these exposure levels. The second highest SAR10 values indicate that the positioning of both the digital humans and the phone has a greater impact on absorption rate levels of the fetus than the presence of the elevator itself. While SARwb values are typically low for the fetus, most measurements reveal a noticeable increase in the peak values inside the metallic elevator cabin. The distance between the phone and the fetus, and the interference of other tissues from the figures of Pregnant II and Roberta are the main factors affecting the absorption rate level of the fetus. It should be underlined, that in all studied scenarios, the temperature increase for pregnant women and fetuses remains well below 1 \({}^{\circ}\)C, the threshold associated with health issues in animal fetuses, as noted by the WHO [72]. When comparing the results in this work with the previous study [55], differences are noted. For example, in [55], Roberta SAR10g increases as the phone transitions from a parallel position to a tilt and finally to the cheek. In the current study, however, specific absorption rate follows a different pattern, rising from the tilt position to parallel and then to the cheek. In addition, ref. [55] exhibits a higher peak local absorption density at 1000 MHz. Still, Tmax remains nearly identical between the two studies, with significantly higher values at the cheek compared to the tilt and parallel positions. Additionally, the maximum and minimum values across both studies are closely aligned. At 1800 MHz, both SAR10g and Tmax follow the same trends, with identical maximum and minimum values occurring at the same phone positions. As far as SARwb is concerned, similar values and distribution in both studies for Roberta are calculated. Even if higher SARwb is found in some measurements than [55], the differences are very small, and the values match each other. In contrast to [PERSON]'s calculations regarding the gestational body, the highest EM absorption intensity and maximum thermal intensity values at 1000 MHz are found in the same configuration for both studies; that is, when the handset is in a tilt position and when the distance between the child and the pregnant numerical phantom is minimized. Yet, in this study, the peak SAR and Tmax values are higher than those in the previous study [55]. Furthermore, the whole-body specific absorption rate for pregnant women is influenced by the portable telecommunication device position and also by human position, while in [55] it is influenced mostly by phone position. The values here are also similar to each other in the two studies. Finally, for fetal exposure, this study finds higher maximum values across all frequencies as compared to a previous study [55]. The distribution pattern mirrors that of the Pregnant II model, whereas in a previous study [55], it differed. Notably, in both studies, all fetal maximum values are concentrated in the amniotic fluid.
