APPARATUS FOR CONTROLLING ACCESS AND LEAVING REGION OF RADIATION CONTROL AREA

摘要

PURPOSE:To make it possible to notify an excess of an exposure dose beforehand, by connecting an environmental radiation measuring data control apparatus to an access and leaving a region control apparatus to calculate an exposure dose estimate value. CONSTITUTION:Input machinery 5, tolerance exposure dose input machinery 6 and control area work planning information input machinery 7 are connected to an entry region limiting gate and various data are inputted to a calculator 13 through an input interface (IF)12 by the operation of an entry person. An environmental radiation measuring data control apparatus 11 is connected to the calculator 13 through IF12 and space dose rate measuring data periodic or renewed at a proper time is inputted to the calculator 13 along with a measuring place. The calculator 13 processes these data not only to operate a drive apparatus 3 through an output IF14 but also to display the exposure dose estimate value and exposure dose excess notification to a working plan on a display device 15. Input machineries 8-10 are connected to an exit region limiting gate 2 and data are inputted to the calculator 13 through IF12 by the operation of an exit person and processed by the calculator 13 not only to operate a drive apparatus 4 through IF14 but also to display an exposure dose result value.
