Potential exposure assessment errors associated with body-worn RF dosimeters

Bioelectromagnetics. 2007 Oct;28(7):573-6. doi: 10.1002/bem.20355.


Personal exposure meters for assessing exposure to RF electric or magnetic fields are subject to errors associated with perturbations of the fields by the presence of the human body. Although these alterations are complex they are not completely unpredictable. This article concludes that this error in a common worst-case scenario could reach up to 30 dB and therefore is of concern for exposure assessment. We present several guidelines to address this issue and a useful insight into the overall problem based on finite-difference time-domain simulations and experimental verification.
