LB 2046 Portable Alpha-Beta-Measurement System Description：

Product Manual

The Alpha-Beta-measuring station LB 2046 or LB 2046-130 was developed for the simultaneous determination of alpha and beta activities in different measuring samples, e.g. in nuclear or nuclear chemical plants, as wipe tests or as residuals of evaporation. In the same way, general environmental samples or filters from dusting units can be tested for their activity.

The large area ZnS(Ag) scintillation detector with a diameter of 60 mm or 130 mm is best suited for the measurement of alpha- and beta/gamma-radiation and is covered by a light-proof, aluminized hostaphan foil (0.4 mg/cm2).

The touch sensitive graphic display offers an intuitive user interface with simple and fast access to important measuring routines: With the background routine the Alpha and Beta background subtraction is provided and stored for the correction of the measured value. The calibration routine permits the calibration of the detector for different nuclides. With the system test a performance check for the instrument can quickly be achieved.
