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

Conventional Probes & Connectivity

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