The exposure of an 8-years child moving in a room to a 4G LTE femtocell with uncertain position was assessed by stochastic dosimetry based on sparse low rank tensor approximation method (sparse LRA). The Specific Absorption Rate (SAR) was estimated in all the possible positions of femtocell and child. Results showed that, for all the possible positions in the room, the exposure values were significantly below the International Commission of Non-Ionizing Radiation Protection (ICNIRP) guidelines for general public exposure. The variation of the distance between femtocell and child influenced greatly the exposure, resulting in Quartile Coefficient of Dispersion value equal to 67%.

Abstract
The exposure of an 8-years child moving in a room to a 4G LTE femtocell with uncertain position was assessed by stochastic dosimetry based on sparse low rank tensor approximation method (sparse LRA). The Specific Absorption Rate (SAR) was estimated in all the possible positions of femtocell and child. Results showed that, for all the possible positions in the room, the exposure values were significantly below the International Commission of Non-Ionizing Radiation Protection (ICNIRP) guidelines for general public exposure. The variation of the distance between femtocell and child influenced greatly the exposure, resulting in Quartile Coefficient of Dispersion value equal to 67%.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
