LB 790 10-Channel α-β Low-Level Counter with PC-Software AMS

LB790The 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) (according to ISO
11929; 1 h measuring time)1).LB790 STAND

 

1)  Detection limit is calculated regardless of spillover and calibration uncertainty.

Measuring times (sample = background), 5% error probability, background value of 0.1 cpm for Alpha and 1 cpm for Beta.

For Am-241 an efficiency of 34% and for Sr-90 an efficiency of 50% is used.
