摘要： PROBLEM TO BE SOLVED: To provide a radiation measurement apparatus for surely preventing a malfunction due to incoming noise, and suppressing a substantial missing time during a measurement at the minimum when a signal is processed so as to prevent the malfunction.
SOLUTION: A count value of a first counter 3 and a count value of a second counter 6 are compared. If a comparison result is increased and deviated from a predetermined allowable range, it determines that noise is detected. A count rate obtained for a previous calculation period is employed as a count rate obtained for a current calculation period while the noise exists. If the comparison result recovers the allowable range, it determines that there is no incoming noise. A backup count rate calculated based on the count value of the first counter 3 is employed as the count rate for the current calculation period until a regular count rate based on an accumulation value of an up-down counter 7 is normally recovered.
