New remote display for the radiation monitoring equipment and documentation system for the large hot cells of KFA Juelich

The radiation monitoring equipment of the large hot cells consists of area monitors for gamma radiation at the various working places in the house and of mobile air monitoring facilities giving information about the occurrence of aerosols. In total 19 area monitors and 6 air monitors are operating. The measured values from these instruments are transferred to the control room of the hot cells and displayed there. These displays are being cyclically called by a microprocessor. All exceedings of preselectable limits are displayed and stored together with time and date. They may be called at every time. A central microprocessor collects such deviations and partially the associated measured values and sets up records in selectable intervals (day, week, month). This central processor can record the data of five equivalent monitoring facilities - as described above. (orig./HP)
