ID Number		684
Study Type		Human / Provocation
Model		Non-RF (conventional) heating of test subject hands and analysis of heat transfer properties
Details		Human subjects submerged their wrist in water of various temperatures for 30 minutes to determine heat transfer properties. The study revealed heat transfer rate increased with increasing age, possibly as a result of an age-dependent increase in blood flow through the hands and wrists in response to local heating. In addition, localized blood flow was found to increase linearly with temperature. Although RF exposure would be expected to induce a different heating pattern than conventional (conducted, convective, radiant) heating, the equilibrium temperature (threshold for tissue heating) would be above the 20 W/kg limit proposed by the NRPB for operators of dielectric heaters. Such exposure would not be expected to induce tissue temperatures in excess of 40.9 C.
