FLOOR MONITORS ALPHA plus BETA-GAMMA

Model # ABFM-5 Pancake Array GM

Model # ABFM-6 Scintillator

Model # ABFM-7 Gas Flow

FEATURES: SEPARATES ALPHA FROM BETA-GAMMA IN ABFM-6 AND ABFM-7 LARGE FACE 144 square inches (925 cm2) on ABFM6 and ABFM7 SCINTILLATION, GAS FLOW, or GM DETECTOR FAST AND SENSITIVE ANALOG AND DIGITAL READOUT OUTPUT FOR RECORDER RUGGED BUILT-IN SPEAKER CAN BE DECONTAMINATED GENERAL DESCRIPTION: Alpha plus Beta Gamma Floor Monitors, Models ABFM-5, 6, & 7 utilize alpha-beta-gamma sensitive detectors coupled to appropriate electronics. An electronic sorter accepts and displays alpha counts only or alphas plus beta-gamma, or beta-gamma only. Windows are protected by a frame and grid which may be easily removed for decontamination purposes. The very large face detectors achieve, as far as we know, the fastest most sensitive floor monitoring system currently available.
