A combination of a master machine and a plurality of slave machines communicate wireless with each other. In case of a radiation leak accident, multitudes of inhabitants or workers dealing with the accident are made to carry the slave machines. The slave machine measure the degree of radiation exposure in real time, and notifies this measured result automatically to the master machine by wireless communication. The master machine recognizes the accurate radiation dose of the exposure and determines the degree of danger. The master machine notifies in real time the determined result individually to people carrying the slave machine, who are exposed victims or people that have a possibility of being exposed, according to the danger degree. The master machine is made to extract true radiation measurement data from the measurement signal data sent by the slave machine, by discriminating noise. This true radiation measurement data is made to be compared to a previously prescribed safety standard data, and the danger degree is determined. An alarm signal is made so that it can be transmitted to the slave machine, according to the determined result.
