Cs 137 Gamma Spectrum This spectrum was taken from a 1 µC 137Cs check source, using a GS-1100-PRO with a new 2 x 2" Gammaspectacular detector and PRA software . The 32 KeV x-ray peak and the 662 keV gamma peak are very obvious, and as there is a good spread between the peaks, this source makes for a good calibration source.

The radioactive material is chemically plated on to the surface of a silver disk that is mounted at the bottom of the well of a Plexiglas® disk. The completed sources are unsealed and offered in two sizes: 1.0” x 0.125” and 2.0” x 0.125”. All alpha disk sources have an uncertainty of ± 20% of the labeled activity.

GAMMA-SPECTRA Figure 1. - Idealized Picture of Gamma-Ray Spectrum Showing Only the Photopeak SCINTILLATION SPECTRA The Photopeak If you were to place a monoenergetic source of gamma-rays ( e.g., 137Cs) near a scintillation detector, you expect, ideally, a spectrum which is a single photopeak caused by the photoelectric effect in the Beta Ray (Electron) Energy Spectrum . Columbia Physics: Lab 2 -10 (ver. 10) 3 The basic counter circuit, shown in Figure 4, supplies a positive high voltage of up to 900 volts to the center wire. Ad ditionally, there will be some excess counts due to the Cs -137 .
