That’s a great way to estimate the neutron fluence (which is neutron flux integrated over time). So, if we can estimate the neutron fluence of my sample, and since we know how neutrons are emitted by the explosion at different distances, we can estimate how far away from ground zero my sample came from . Thorium 232. The Th232 Gamma Spectrum, has many peaks stretching out to 2.6 MeV, and it can be tricky to identify the correct peaks.

Gamma-ray spectroscopy is the quantitative study of the energy spectra of gamma-ray sources, such as in the nuclear industry, geochemical investigation, and astrophysics.. Most radioactive sources produce gamma rays, which are of various energies and intensities. When these emissions are detected and analyzed with a spectroscopy system, a gamma-ray energy spectrum can be produced.
If higher energy gamma rays must be seen, the gain is lowered. Se hela listan på de.wikipedia.org Figure 2.6: standard spectra of 152Eu, 56Co and background normalized for one hour. Figure 2.7: simplified decay scheme showing the effect of summing in and out.

Gamma-Neutron Sources 23 ggg • The overall shape of the source might be cylindrical or spherical. • In the case of an antimony-beryllium source, the core is antimony that has been activated in a reactor. Europium-152 is suggested as a nuclide of choice in hard-gamma brachytherapy .
I've been desperately Googling any query I can think of to find the
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.

To reduce gamma rays, an anticoincidence shield can be used—see Compton suppression. Gamma ray reduction techniques are especially useful for small lithium-doped germanium (Ge(Li)) detectors. The gamma spectrum shown in Figure 2 is of the cobalt isotope 60 Co, with two gamma rays with 1.17 MeV and 1.33 MeV respectively.
