PROBLEM TO BE SOLVED: To provide a system which measures radiation exposure of many dwellers and accident countermeasure workers in a realtime manner in the case of radiation leakage accident, recognizes accurate radiation exposure, judges danger, and can inform individually the results in response to the degree of danger as alarms in a realtime manner. SOLUTION: This system consists of a master device 1 and a plurality of subordinate devices 2 which are capable of mutual wireless communication. The subordinate device 2 can sense radiation, convert it into a measurement signal data, transmit and receive an electric signal data including the measurement signal data, and display an output of alarm (danger/safety) by receiving an alarm signal from the master device 1. The master device 1 discriminates noise from the measurement signal data transmitted from the subordinate device 2, extracts true radiant ray data, compares the data with previously determined safety reference, judges the degree of danger, and transmits an alarm signal to the subordinate device in response to the judged result. |
