Berthold - Model LB 790 / LB 761 - Alpha Beta Low Level Counter - Brochure

The 10-Channel Low-Level Counter LB 790 allows simultaneous and separate measurements of low activities for alpha and beta radiation emitting radionuclides with a detection limit of approx. 12 mBq for Alpha (Am-241) and approx. 22 mBq for Beta (Sr-90). The measuring system LB 761 Alpha-Beta Low-Level Counter for 200 mm Planchets allows the simultaneous measurement of alpha- and Beta- activity of a sample in two separate measuring channels. The background count-rates of the system LB 761 are extraordinarily low, so that good detection limits can be achieved.
