Set of 8 gamma emitting isotopes covering the entire energy range from 32 to 1333 keV. Also includes a mixed source of Cs-137 and Zn-65 which students may use to identify an “unknown” isotope. The set consists of Ba-133, Cd-109, Co-57, Co-60, Cs-137, Mn-54. Na-22 and Cs/Zn
Geiger Counter, Versatile, easy to use and compact precision instrument for measuring alpha-, beta- and gamma-radiation. Filter selection switch at the front of the Geiger-Muller counter tube for filtering out types of radiation
Radiation set of three sources contains 1 each Po-210, Sr-90 and Co-60 emitting alpha, beta and gamma radiation's. Ideal for demonstration and nuclear labs covering basic characteristics of radiation. The Co-60 is 1 uCi and the Po-210 and Sr-90 are 0.1 uCi activity.
