Summary:
This paper presents the dosimetric evaluation of the infant s exposure to electromagnetic fields from an electronic article surveillance system working at 125 kHz. A recently developed realistic infant anatomical model is deformed to achieve the standing, sitting and the supine postures. We perform the quasi-static calculation for the 99th percentile induced electric field, the peak specific absorption rate averaging over 10 g tissue and the maximum induced current density. A comparison has been made with the adult. The results show that the postures and the effective exposed part are very important factors for the dose results. The infant is not always overexposed compared with the adult. The magnetic field acquired by two popular methods can not be used for guidelines compliance evaluation.
