Personal, Non-Invasive Dosimetry for Radio-Frequency Human Exposure Assessment

The integrity of data gathered by a body worn personal radiofrequency exposure meter has been investigated using computational methods. Simulations show that the distortion of the field by the body will cause measurement errors with a traditional 3-axis dipole field sensor. A modified measurement method for body worn personal exposure meters based on an array of 2-axis dipole field sensors is proposed. The approach minimizes the impact of body shielding (shadowing of the field) and could provide information on the average internal specific absorption rate (SAR) in various parts of the body.
