Stochastic Dosimetry for the Assessment of the Fetal Exposure to 4G LTE Tablet in Realistic Scenarios

In this study, we used stochastic dosimetry, a promising approach that combines electromagnetic computational techniques and statistics, to assess the exposure of a fetus at 9 months of gestational age to a 4G LTE tablet in realistic scenarios characterized by variability. In particular, we analyzed how the exposure changes when moving the tablet in a range of positions representative of realistic exposure scenarios. Polynomial chaos theory, applied to build surrogate models of Specific Absorption Rate (SAR), permitted a fast estimation of the variability of the exposure due to the variation in the tablet position.
