PRESENT KNOWLEDGE ABOUT SPECIFIC ABSORPTION RATES INSIDE A HUMAN-BODYEXPOSED TO RADIOFREQUENCY ELECTROMAGNETIC-FIELDS

We have compiled results of scientific investigations about the relati onship between external held-strengths and specific absorption rates i nside the human body. The data were normalized to SAR-values that form the basis for current safety standards. Results were compared to expo sure limits given in these standards. This comparison should serve as a reference for the selection of reliable reference levels for persona l protection against thermal effects in radiofrequency electromagnetic fields. The need to measure and monitor ankle/wrist currents to prote ct some exposed workers is explained. The study has also highlighted a scarcity of dosimetric data at frequencies below 3 MHz.
