Abstract:
We depict a method of determination of the size D depth z and temperature T0 + delta T of a cylindrical thermal structure embedded in an homogeneous glossy material, in the present case, water. A microwave radiometric image at 3 GHz points out the location of the thermal structure; its threshold provides the diameter D of the structure. The depth z derives from the ratio of the maximal radiometric intensities at 1.5 and 3 GHz. The combination of D,z and of the radiometric intensities gives delta T.

Equipments Used to Measure Body Temperature
Glass-bulb Thermometer:
Glass-bulb thermometers are hollow glass tubes with a bulb tip containing liquid such as ethanol or mercury. Historically, glass bulb mercury thermometers were the standard device to measure body temperature. Today, mercury thermometers are prohibited in many countries due to the hazardous effects of mercury and the risk of exposure if the glass bulb breaks. In general,...
