FHZ 742
$0.00
The Thermo Scientific FHZ 742 is a scintillator contamination probe designed for surface alpha and beta radiation detection with FH 40 G systems.
The FHZ 742 is an external surface contamination detector probe used for measuring alpha and beta radiation contamination. It features a ZnS scintillation detector with a sensitive area of approximately 125 cm². The probe provides high efficiency for alpha detection (40% for Am-241) and beta detection (56% for Sr/Y-90). It includes specifications for window thickness (0.87 mg/cm²) with a window size of 100mm × 125mm. The probe is compatible with the FH 40 G radiation measurement system and FHT 6020 display unit. Applications include surface contamination surveys and environmental monitoring.
