<p>PROBLEM TO BE SOLVED: To reduce working man-hours by mechanically discriminating the presence or absence of abnormality in radiation environment, when carrying out periodical inspection in nuclear power stations or the like. SOLUTION: This radiation environment monitoring system is composed of a wireless radiation measurement device 1, a control device 5, a storage device 4 that are installed in a working place, and radiation state display parts 6 and 7 that are installed in the working place and a control room. The change forecast value of the dose equivalent weight rate of the working place is kept in time series (for each working step or the like), and a measurement value, measured by a measuring instrument placed at a plurality of places, is compared with the next change forecast value in time series, thus judging the degree of progress in time series, continuously comparing an estimated dose equivalent weight rate in matching with the degree of progress with the measurement value at all times, and monitoring and displaying the presence or absence of the abnormality of the dose equivalent weight rate of the working place.</p> |
