RADIATION MEASUREMENT DEVICE

摘要

A first calculation unit calculates a moving average (dose rate) using a relatively long averaging period (T). A second calculation unit calculates an integrated value (dose rate) using a relatively short time constant (Ä). In a state in which the moving average is displayed, an alarm determination unit identifies a dose abnormality on the basis of the integrated value. Within a measurement start period, a display switching determination unit identifies a constant dose rate state on the basis of the integrated value. A restoration determination unit identifies the restoration of a dose rate on the basis of the integrated value. If a dose rate is displayed using a large degree of smoothing, sudden increases, and the like, in the dose rate can be identified quickly.
