LOW-LEVEL BETA GM Multicounter System Model RISO GM-25-5

1,Specifications

Sample size：25mm. diameter　

Background in 100mm lead shield：<0.2CPM(typically<0.15CPM)

Efficiency:   90Sr/Y:   54%

             36Cl   :   44%

             99Tc   :   42%

2, Principle and application

Low-level gas flow beta multicounter system measure 5 samples simultaneously. The multicounter is normally placed inside a lead shielding of 100 mm thickness to reduce the ambient background radiation.
