Abstract

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.
