DOSAGE RATE MEASUREMENT DEVICE

A dose rate monitoring device includes: a first energy compensation coefficient operation part obtaining a first energy compensation coefficient to incident radiation using the first compensation coefficient table, a first dose rate operation part obtaining a first compensation dose rate of incident radiation using the first energy compensation coefficient and G (E) function, a second energy compensation coefficient operation part obtaining a second energy compensation coefficient to incident radiation using a second compensation coefficient table, a second dose rate operation part obtaining a second compensation dose rate of incident radiation using a second energy compensation coefficient, a dose rate switching section which select an output according to the magnitude of a ratio of the first compensation dose rate to the second compensation dose rate, and a display operating section which displays the first compensation dose rate or the second compensation dose rate which the dose rate switching section outputs.
