1. A radiation clinical thermometer comprising:

  • a probe including an optical system constituted by focusing means for focusing infrared radiation from an object to be measured and a filter having transmission wavelength characteristics, an infrared sensor for converting infrared radiation energy into an electrical signal, and a temperature-sensitive sensor for measuring a temperature of said infrared sensor and an ambient temperature thereof;

    detection signal processing means for receiving electrical signals from said infrared sensor and said temperature-sensitive sensor and outputting the electrical signals as digital infrared data and temperature-sensitive data, respectively;

    body temperature operating means for calculating body temperature data; and

    a display unit for displaying a body temperature in accordance with the body temperature data, including filter correcting means for setting a correction value based on the transmission wavelength characteristics of said filter, wherein said body temperature operating means receives the infrared data, the temperature-sensitive data, and the correction value from said filter correcting means so as to calculate body temperature data.
