Features
The Model 190-100BGS is a large area scintillation detector suitable for measurement of beta particles and low energy gamma radiation.
The probe has high efficiencies for key isotopes used in the nuclear medicine field. This detector, coupled with the ASM-990, makes a particularly effective measurement solution.
Applications
The Model 190-100BGS is designed to measure isotopes that are typically found in hospital nuclear medicine departments, radiopharmaceutical production facilities, and environmental surveying applications where large surface area Beta/Gamma detectors are required.
