[en] J-PARC radiation-monitoring system was developed as a part of safety facilities, thus, it is isolated and has been operated independently from the accelerator controls. During 2013-2014, we have developed device-level data-link layers to enable one-way data transfer from the radiation-monitoring system to the accelerator control system. As a result, all of the radiation monitors can be supervised from the accelerator controls. Based on this new scheme, a GUI application, 'RadAccSafety', has been developed. It is designed for accelerator operators to inform over-all radiation-monitoring levels whether they are below the alarm thresholds or not. In a case of an alarm event, it provides information on the alarm locations, severity levels (caution, alert, or normal), 2-hour and 10- hour trend graphs, time-series log of alarm events, and so on. This report describes details of 'RadAccSafety' screens, as well as some operation experiences. (author)
