Title: Microsoft Word - gamma_ray_spectroscopy.doc Author: MJL Created Date: 3/13/2006 3:59:46 PM If only one of these gamma-rays escapes while the other is completely absorbed in the detector, 511 keV will be lost from the detector. This results in a separate peak in the spectrum representing Eg-511 keV, called the single escape peak. In addition to the features described above, the response of a gamma-ray detector has additional features created by surrounding materials. An example is shown in Fig. 5.11, which is a 24Na gamma-ray spectrum collected in the MedPhys 4R06 multi-channel analyzer lab.

Gamma Emitters The following is a listing of selected (greater than 100 million electron volt or “MeV”) radionuclides, ordered by element, that emit gamma ray photons during radioactive decay. Each entry gives the radionuclide symbol (i.e., I-131), followed by the photon energy (in units of MeV), followed by the photon yield (i.e., probability per decay).

The gamma spectrum is characteristic of the gamma-emitting nuclides contained in the source, just as in optical spectroscopy, the optical spectrum is characteristic of the material contained in a sample. Gamma-ray characteristics Gamma rays are the highest-energy form of electromagnetic radiation, being physically the same all other The β + spectrum of Na 22 was measured with a scintillation spectrometer. To avoid source absorption and scattering troubles the Na 22 source was built in in the lattice of NaI(Tl) crystals.

The HPGe detector allows the separation of many Gamma Ray Dose Constants. The “Specific Gamma Ray Dose Constant”, sometimes known as the “Gamma Factor”, is the dose rate at a specific distance from a given amount of a photon-emitting radionuclide. These constants are used frequently for radiation protection purposes.

These constants are used frequently for radiation protection purposes. The following is a listing of Specific Gamma Ray Dose Constants for Gamma rays falling into this case would contribute a peak on the gamma spectrum, with energy equal to E’: It is also possible for a gamma ray to enter, and electron-positron pair-production to occur. The original energy of the gamma ray would be transformed into the energies of an electron and a positron.

In summary, this investigation shows that the radiation from Cs"'consists of a simple beta-ray spectrum with an end point at 0.550-Mev energy and a single gamma-ray of annihilation gamma. This is a special spectrum, it was taken with PRA 5.0 using two sodium iodide detectors, in coincidence counting mode, to detect the annihilation gammas that are produced when 22Na undergoes beta+ decay. The positron instantly annihilates with an electron, producing two 511 keV gammas at a 180˚ angle.
