LB 124 SCINT Contamination Monitor for Alpha- and Beta-Gamma-Measurement

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

Probes & Connectivity

Additional Dose Rate Detector (LB 124 SCINT-D)
Xenon filled proportional counter technology (LB 124 B)
RS232 interface
Headphone connection
