Isotope Disk set, 8 disk
Designed for in-depth nuclear sudies and gamma spectroscopy, our 8 disk set contains different gamma emitting isotopes covering the entire energy range from 32 to 1333 keV. Also included in the set is a mixed source of Cs-137 and Zn-65, which if being used for classroom instruction, students may use to identify an “unknown” isotope.

Contains 1 each of Ba-133, Cd-109, Co-57, Co-60, Cs-137, Mn-54. Na-22 and Cs/Zn. Source activities are all 1 uCi, except the Cs/Zn source, which is 0.5 uCi Cs, and 1 uCi Zn.
Half-Life and emission energies are as follows:
