Title:
TEMPERATURE-COMPENSATED TYPE OPTICAL TRANSMISSION FORM APPARATUS FOR MEASURING RADIATION AND MEASUREMENT SYSTEM THEREOF
Document Type and Number:
Japanese Patent JP2001141830
Kind Code:
A
Abstract:
To provide a practical apparatus which permits temperature compensation of a scintillator emission intensity in an optical transmission type a radiation-measuring apparatus.
A transmission medium fiber for transmitting the light of the optical transmission type radiation-measuring apparatus is used also for transmitting light for an OTDR temperature measurement, so that the scintillation emission intensity can be effectively temperature compensated. The practical apparatus and its measurement system, which can correctly temperature compensate the scintillation emission intensity in a long distance optical transmission type radiation-measuring apparatus, can thus be realized.
