Service & reparation Request a quoteThe portable Alpha-Beta Activity Measuring System LB 2046 offers the simultaneous and separate measurement of alpha- and beta-activities in different sample types for various applications, like smear tests or as planchet sample residues. Environmental samples as well as filters from air sampling units can be measured in the same way.
The LB 2046 has a scintillation detector with 60 mm diameter. The samples to be measured are placed on a sliding drawer which allows a planchet diameter of up to 60 mm and a height of up to 8 mm. Also filters with diameters of 60 and 100 mm can be measured by means of the filter adapter (optional). The detector provides simultaneous and separate determination of the alpha and beta activity with a detection limit (according to ISO 11929 in 1 h measuring time) of approx. 0.07 Bq for alphas (Am-241) respectively 0.14 Bq for betas (Cl-36).
- Simultaneous and separate Alpha- and Beta measurement
