Compton Scattering of Cs-137 Gamma Rays

Fichier PDF

Compton scattering experiment with Cs–137 gamma 77, rays is complicated by the need for an intense source, license, shielding and collimation, and a means of measuring gamma energies of the scattered rays as a function of the scattering angle, In this instance a 30 millicurie Cs–137 is used for the gamma source, The source is located in a lead howitzer that is used to shield personnel from

The Rich Physics of Cs-137 Gamma Spectrum – Maximus Energy

137 Cs Decay Modes, Let’s start by examining a very-well known cesium-137 decay diagram – Fig, 1, Fig, 1, Cs–137 beta decay modes, 180 keV with the energy of the Compton edge 482 keV adds up to the the energy of the photopeak 662 keV, Fig, 4 is adapted from this excellent paper, which gives an example of how one can enhance the Compton peak by locating a thick slab of …

PDF Observing Compton Scattering with Caesium-137 gamma-rays

Compton have been replaced with high-energy gamma rays, with an energy of around 0,662 MeV emitted from a, Caesium-137 source, the choice of gamma rays is due to the, stable nature of their

Cs 137 Gamma Spectrum 137Cs

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, Note the area between the peaks, showing Compton the …

Use the Cs–137 source to record a test spectrum with the MCA and check if you receive a spectrum of the expected form, The photopeak in the spectrum represents the 661,6 keV photon energy of Cs–137, you should also see the Compton–edge, To measure the unknown energy of photons, it is necessary to calibrate the MCA, Use the following

What causes the *other* Compton edge?

The region between the Compton edge and the backscatter peak is the region where secondary photons scattered at medium angles are displayed, And your algebra is wrong! You cannot throw a 1 in there, Do the math with a real energy and see if you get corresponding results, Plus, I did the calculation for Cs–137 and it matches the spectrum

Compton edge calculated in Table 1, Back Scattering Peak Gamma-rays from the source hit the aluminum shielding around the NaI crystal and undergo, Compton Scattering, The scattered photons, or secondary photons, are de ected backwards into the detector, Since these photons carry energy less than the original Gamma-ray pho- tons, they undergo Photoelectric e ect in the NaI Crystal depositing

The Analysis Pulse-Height Spectrometry

Compton plateau – is the area just before the Compton edge; Compton edge – is the area just before the Compton valley; Compton valley – is the area/valley just before the photopeak; Ba x-ray peak – is emitted by 137 Cs atom; Photoelectric peak – is the energy of the radionuclide that needs to be recorded; Note the photoelectric peak is looks like Poisson distribution curve and it is not a
