Q4-GR1 – Kromek
Quant for GR1 (Q4-GR1) is a unique solution for measuring the activity of radionuclides in filters, filter papers, and beakers.
The low power, small form factor, reliability, and no requirement for cooling, enable measurements of various configurations of samples, without the need for time consuming transport back to offsite laboratory.
Q4-GR1 utilises mature Cadmium Zinc Telluride (CZT) technology, provides less than 2% energy resolution, unmatched by conventional scintillator detector based instruments such as LaBr3 and NaI. This high resolution performance enables clear separation of gamma energy peaks within complex mixed radionuclide samples for accurate quantification of individual radionuclides without the need for chemical separation.

Q4-GR1 features:

  • detector Resolution: <2%
  • energy Range: 30keV to 3MeV
  • number of channels: 4096
  • weight: 22kg
  • power Consumption: Powered via USB
  • dimensions: 300mm diameter x 210mm height
  • lead/Copper Shield: 10mm/3mm
  • number of selectable radionuclides as standard: 47
  • counting Time: User Configurable
