It is one of the standard units for radiation dosimetry, but is not applicable to alpha, beta, or other particle emission and does not accurately predict the tissue effects of gamma rays of extremely high energies. gamma-detectors around the energy levels 1173 and 1332 keV, which are the main gamma energies of Co 61.

In the spectrum are also visible X emissions from Lutetium and a sum peak at 509keV.

6 Mar 2013 This is a complicated decay with many possible modes--there are one or more gamma associated with every alpha line (except, perhaps the 17 Dec 2016 The figure shows a 241-Am gamma-ray spectrum taken with the small pixel, CdTe-based, HEXITEC X-ray imaging detector system. http://en. 18 Jul 2004 if smoke is present between the Am-241 source and the detector. Am-241 also emits low energy gamma-rays which were measured here. v.

This shown by the presence of epithermal and thermal spectrum is in agreement with a gamma-ray background neutrons. spectrum measured by Petrasso et al. (1989). The count rates, at 100 cm, of the 4.4 MeV gamma Both neutron sources show peaks at 0.2, 0.5, 3.4, 3.9 rays in both neutron sources produce approximately the and 4.4 MeV. The temperature dependence of 241Am in NaI(Tl) was found to be at least four times greater than that of 241Am in both CsI(Tl) and CsI(Na) whose equivalent gamma-ray energies varied by 2 to 3 percent over the temperature range 30"F to 120"F. processes are accompanied by photon radiation. Furthermore the spectrum of fission products contains radioactive elements that produce additional gamma photons. In the .
