ABSTRACT
In any biological experiment involving electromagnetic fields (EMFs), and regardless of the particular mechanisms of how bioeffects are produced, the "extent" of EMF interaction with the living object has to be characterized by certain metrics. One critical feature of thermometers intended for measurements during EMF exposure is their EMF compatibility. Another problem of EMF compatibility results from the fact that temperature sensors have dielectric properties different from those of biological tissues and samples. In real-life situations, specific absorption rate (SAR) measurement errors introduced by indirect heating can be very significant and perhaps sometimes approach the 100" level, like in the hypothetical setting. Microthermocouple (MTC) and HERO are the most suitable probes for high-resolution, quick temperature measurements with minimum local-field distortion. This chapter shows how these probes can be utilized for precision microdosimetry in high-intensity pulsed EMF. The presence of the post exposure plateau means that, at the given location, the dissipation of heat generated by EMF absorption was negligible.
