Source Sets

Our 1-inch alpha, beta, and gamma sources are available in four source sets: S-7 (1 ea. alpha, 1 ea. beta, 1 ea. gamma), S-8 (1 ea. alpha, 2 ea. beta, 2 ea. gamma), S-13 (8 ea. gamma), and S-PTC (6 ea. gamma). The S-13 source set contains eight gamma sources and is especially well suited for scintillation spectroscopy experimentation requiring a wide range of gamma energies. All sets are packaged in sturdy plastic cases suitable for storage. The S-PTC source set contains six gamma sources designed for use with Genie 2000 to perform Peak-To-Total calibration for coincidence summing correction.
