PURPOSE:To enable measurment of the spatial intensity distribution of a radiation while enhancing the utilization rate of light by covering material emitting light while being exposed to heating or light irradiated after the irradiation of radiation with more than one layers of material different in the refraction factor therefrom to form a light wave guide. CONSTITUTION:When radiation heat fluorescent material is used, the light source 11 employs CO2 laser or YAG laser while it utilizes a luminous element containing the wavelength of lambda1=365nm in the emission spectrum when a phosphate glass is used. The light source 11 scans a luminous material 7 with a scanner 12 to generate light from the luminous material 7 according to the dose of the radiation irradiated thereon 7. This light is transmitted to a light wave guide made up of the luminous material 7 and a covering material 8 and reaches a photo detector 9. A signal from the photo detector 9 is inputted into a signal analyzer 13, converted to a radiation intensity distribution using a scanning signal and indicated on a radiation intensity distribution display 14. |
