Ultra-low-level Beta GM Multicounter

Brand: Delta Elektronika | Category: Scientific & Laboratory

The Risø Ultra-low-level Beta GM Multicounter is designed for counting very low activity environmental samples. It uses five flow-through Geiger-Müller pancake detectors with an anti-coincidence guard counter, achieving a background of less than 0.2 cpm inside 10 cm lead shielding. Primarily used for ²³⁶Th analysis in marine sediments and ⁴⁰K activity in feldspar extracts for luminescence dating dose-rate calculations.
