Title:
RADIATION MEASURING APPARATUS
Document Type and Number:
Japanese Patent JP2015158376
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide separately measure a plurality of types of radiations with a simple configuration.SOLUTION: Each photomultiplier tube outputs a detection signal in response to light emitted from a liquid scintillator 10 depending on the detection of a radiation. A level adjustment amplifier 20 and a first MCA 22 constitute a first analysis unit obtaining an energy spectrum based on the detection signal. A second MCA 24 constitutes a second analysis unit obtaining an energy spectrum based on the detection signal. A separate measuring unit 26 obtains a contamination value of radiations other than a measuring target radiation contained in the energy spectrum obtained by the first analysis unit. This contamination value is obtained based on the energy spectrum obtained by the second analysis unit. The separate measuring unit 26 obtains a radiation measuring value of the measuring target radiation using the energy spectrum obtained by the first analysis unit and the contamination value.
