A radiation measurement apparatus 1 includes a radiation sensor 10 that generates a detection signal, a first counter unit 15 that counts the number of the detection signal, an oscillator 16 that generates periodic signal with predetermined period, an AND circuit 17 that outputs logical product obtained by performing AND operation between the detection signal and the periodic signal, a second counter unit 18 that counts the number of a signal output from the AND circuit 17, and a display unit 23 that displays a value counted by the first counter unit 15 when a value counted by the second counter unit 18 is less than predetermined value and a value being different from the value counted by the first counter unit 15 when the value counted by the second counter unit 18 is not less than predetermined value. |
