Highlights
General
- Different detector sizes and types available
- Light, handy and extremely rugged device
- High sensitivity and uniform response
- Calibration factors for over 50 nuclides
- Calibration optionally according to ISO 7503-1 or with reference to an activity of 100 cm2
SCINT Technology
- Unique simultaneous and separate measurement of alpha and beta-gamma radiation
- The individual types of radiation can be distinguished by means of special evaluation and correlation circuits, and thus separated and measured at the same time
- High sensitivity even at low energies
- No counting gas required
