LB 124 SCINT Portable Contamination Monitors Description：

Datasheet User's Manual

The contamination monitor LB 124 SCINT Series, with simultaneous and separate measurement of alpha and beta-gamma radiation, are based on innovative scintillation technology. The compact and precise contamination measuring instruments are versatile and can be used flexibly in practical radiation protection.

The LB 124 SCINT Series have an attractive and ergonomic design and due to their low weights they are easy to handle. The measurement results can be easily read on a large high-resolution display with backlighting, even under unfavourable conditions.

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
