The Gamma‐Ray Counting Efficiency for a Lead‐Cathode G‐M Counter

The dependence of gamma‐ray counting efficiency on energy has been determined in the range 0.17 Mev to 2.76 Mev for a G‐M counter with a lead cathode. The efficiency for six energy values was found by coincidence measurements utilizing the disintegration of In111, Au198, Co60, and Na24. The result i...

Description
Summary:The dependence of gamma‐ray counting efficiency on energy has been determined in the range 0.17 Mev to 2.76 Mev for a G‐M counter with a lead cathode. The efficiency for six energy values was found by coincidence measurements utilizing the disintegration of In111, Au198, Co60, and Na24. The result indicates a smooth increase in counting efficiency for increasing energy over the range of energies investigated.
