PURPOSE:To record a dosage rate to which information on a measurement place is added by providing an indicator device and storing an indicator number sent from the indicator device together with the measured dosage rate. CONSTITUTION:The titled device 100 is arranged on the wall surface in the measurement place set in a radiation control area and a measuring person moves to the specific measurement place and turns on the measurement start switch of a portable dosimeter 200, so that a measurement start signal is radiated as a radio wave from an antenna. The indicator device 100 on receiving the measurement start signal modulates the signal of the indicator number supplied from the marker device 100 and radiates its radio wave from an antenna. The portable dosimeter 200 receives the radio wave of the indicator number and stores the measured dosage rate in a storage circuit 36 together with the indicator number. Consequently, the measuring person only operates the measurement start switch and do not any recording operation, thereby measuring and recording the dosage rate related to the measurement place automatically.
