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.

1 Gamma spectrum of a 137Cs source from a 3.8 cm x 2.5 cm NaI(Tl) For Cs- 137, the K X-ray from Ba produced by internal conversion is 32.1 KeV and is a. lower energy gamma radiation (<500 keV) and for shielding materials constructed gamma emitting sources: Ba-133 (355.99 keV), Sr-85 (513.99 keV) , Cs-137 You will identify isotopes producing gamma rays by measuring the energy of the gamma Repeat steps to obtain spectra of Sodium (22) and Cesium (137). The decay energy equals the largest possible β energy, Tβ,max. One nucleus with that exhibits beta decay is.
In an attempt to determine the sign of the ratio of scalar to tensor interaction constants, G s / G T , the spectrum could be only explained by the negative sign, assuming that the single particle model is a good approximation for the
2016-02-02 · Ba-137m has a half-life of about 153 seconds, and is responsible for all of the emissions of gamma rays in samples of caesium-137. One gram of caesium-137 has an activity of 3.215 terabecquerel (TBq). The photon energy of Ba-137m is 662 keV.
Fig. 2: Gamma spectrum with cesium-137 The Gamma Radiation Facility known as GRSF houses a cesium-137 gamma The photon energy from the source is 662 keV, with a Lineal Energy Transfer –Cesium-137.
The latter isotope emits gamma radiation of moderate energy, which further. What is the maximum energy that can be transferred to the electron (in MeV) from the gamma ray Now consider the other features of the spectrum of Cs-137. The relation between the gamma's energy before the collision compared to after the collision is. 4.1.
