Dilemmas in Measurement of Human Body Temperature

Measurement of human body temperature seems rather trivial until we become parents or medical professionals. If we use different thermometers, which are used at different body sites, inevitably we come across to different measurement results. Then we ask ourselves which result is the right one. The answer is far from trivial because there are a few dilemmas in measurement of human body temperature. To none of these dilemmas exists a straight answer. The article describes dilemmas in measurement of human body temperature and thermometers used for its measurement. Presented are also calibration results of certain clinical radiation thermometers and their improvement in the past few years in terms of accuracy and uncertainty.
