Bulletin No. 168 INSTRUMENTATION FOR NUCLEAR RESEARCH BETA-GAMMA PERSONNEL and LAUNDRY MONITORS Model PPM-8 Portal Type 0 Model LIM-18 Laundry Type 0 Alarm lights on portal and meter indicators on console panel provide double check on location of contamination. Lead shielding around individual detectors minimizes background. Watertight threshold with detachable plastic foot mat for easy decontamination. Audible (buzzer) and visual (red light) alarms. Eight separate counting rate circuit channels with individual alarm settings. 0 Single button to reset all channels. 0 Single H. Y. power supply for all channels. 0 Easy-to-service console cabinet. APPLICATION: Model PPM-8 Portal Monitor provides a quick, efficient, economical method of “head to toe” monitoring of personnel entering or leaving an area. To prevent the spread of contamination, the Portal Monitor is placed at a control point so that personnel entering or leaving the controlled area pass through the portal. Should the contamination on any person passing through the portal exceed a preset radiation level, immediate detection and alarm will result. OPERATION: No skill is required by personnel being monitored. As person passes through the portal, any detected change in the level of radiation at 8 different body areas is indicated on a corresponding meter. An audible alarm sounds when the preset radiation level is exceeded, and indicator lights on both portal.and console panel glow “RED” to indicate the exact spots of contamination. The inside dimension of the portal is purposely narrow to prevent personnel from moving through too rapidly to complete a good check; however, passage can usually be made at 2-second intervals. SEVEN DETECTORS are locate around the sides and top of PO to check head, shoulders, wais and four detectors are groupe in the threshold to check the soles and heels of shoes. The insert at right shows the lead shielding behind each individual detector (T/A # 1 1 20 Tube) in portal. This shielding minimizes the background count.
