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 1408 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, Eu-152. Na-22 and Cs/Zn. Source activities are all 1 uCi, except for the Cs/Zn source and the Eu152 source. Activity levels are as follows: 0.5 uCi Cs, 1 uCi Zn, and 0.5 uCi Eu.
Half-Life and emission energies are as follows:
