The objective of this paper is very simple, namely, to quantify the discrepancies between SAR levels applied during in vitro experiments and actual SAR levels observed in vivo.
The main findings can be summarized as follows:
- The exposure of skin, blood, and muscle tissues with devices satisfying the regulatory safety criteria may well exceed 40 W/kg at the cellular level
- In 51 of the 80 in vitro studies reviewed, the highest exposure level averaged over the cell medium including evaluated cells (monolayer or suspension) was 2 W/kg or less
- It is recommended to include additional exposure levels well above 2 W/kg for any future experiments involving risk assessments (it shall be noted that this recommendation had been made by the authors already at the beginning of the research on risk assessment of mobile communications).
