PROBLEM TO BE SOLVED: To solve a problem of a radiation monitoring device used in a nuclear facility or the like, wherein there is risk that failure of the central monitoring device leads to loss of a monitoring function of all measurement points because centrally monitoring radiation levels of the large number of measurement points in a central control room, and to provide a high-reliability radiation monitoring device reducing influence of the failure to keep soundness of the other functions even when the failure occurs in a part of function of the monitoring device. SOLUTION: This device comprises: a plurality of monitoring modules 2-1, 2-2 to 2-N provided correspondingly to a plurality of radiation detectors 1-1, 1-2 to 1-N respectively installed in a plurality of radiation measurement fields, each having an arithmetic part 11 computing a radiation dose on the basis of measurement data from each the radiation detector 1-1, 1-2 to 1-N, and each having a monitor function; and a common module 4 connected to the plurality of monitoring modules 2-1, 2-2 to 2-N, having a common function. The monitor function and the common function are separated from each other, and each the monitoring module 2-1, 2-2 to 2-N is made to have the monitor function. COPYRIGHT: (C)2006,JPO&NCIPI
