✦ Synopsis

Abstraet--A mathematical model is proposed to understand the sensitivity of internal temperature measurements recorded by thermocouples during microwave heating experiments. In situations of internal heating, such as when microwaves are used, the portion of the metal thermocouple guard protruding from the material body remains relatively cool and represents an effective path for thermal loss. This suggests that the tempera'rare recorded at the tip of the embedded portion of the thermocouple may be strongly dependent on the abiliLy of the metal guard to transfer heat away from this tip. The analytical results derived here support this thesis.

**Summary** In spite of the much shorter thawing times, the use of microwave devices for heating units of fresh frozen plasma is still being discussed. Concerns about general and localised overheating are the main arguments against the use of microwave devices. We evaluated the warming of fresh froz

We consider the thermal response times for heating of tissue subject to nonionizing (microwave or infrared) radiation. The analysis is based on a dimensionless form of the bioheat equation. The thermal response is governed by two time constants: one (t 1 ) pertains to heat convection by blood flow,

Nonuniform heating may result from microwave (MW) irradiation of tissues and is therefore important to investigate in terms of health and safety issues. Hypothalamic (T hyp ), cortical (T ctx ), tympanic (T ty ), and rectal (T re ) temperatures were measured in rats exposed in the far field, k-polar
