Using a whole-body phantom to investigate the effects of positioning on RF personal exposimetry measurements

Abstract : It is unclear how the presence of the human body effects personal exposimetry measurements. To test this, Satimo EME Spy 140 PEMs were placed on a whole-body phantom, measuring the ambient field, then the resulting data were compared to reference measurements done at the same time. By averaging the relative data, intra-day variations and noise cancel out and position-related coefficients can be derived. Differences as high as 12 dB were found, however, no clear pattern can be discerned.
