Abstract:

Human whole-body RF absorption tests have been measured as a function of body orientation, wave impedance, separation from ground, and frequency from 3 to 40 MHz. Results applicable to RF radiation protection are summarized. The worst-case practical exposure situation is taken to be the far-field whole-body exposure of a man wearing footwear and standing on a ground plane. Assuming that 0.4 Wkg is a safe whole-body specific absorption rate SAR, the permitted exposure levels FELs set by the 1982 ANSI standard are well supported by our results. On the other hand, the PELs set by NATO STANAG 2345 are unsafe at most frequencies from 5 to 40 MHz. RF currents through the feet of grounded subjects were also measured. For the maximum exposures permitted by the ANSI standard, the RF currents cause a localized SAR in the ankle region of 16 Wkg.
