The gamma-ray spectrum of plutonium varies greatly with isotopic composition and 241Am con- centration. Two sample spectra are shown in Figures 8.3 and 8.4. Figure 8.3 represents low burnup and low 241Am; Figure 8.4 represents intermediate burnup and relatively high 241Am.

Since then, ORTEC has expanded the product line … 241Am (Americium) Americium is a man made radioactive isotope, and is commonly found in smoke detectors. The source is an alpha emitter, and in the decay process it also kicks out a gamma at 59.6KeV. This is a typical gamma spectrum from Americium, as you can see, the tall peak at 59.6 KeV is very obvious and over powers everything else, it also LETTER TO THE EDITOR Journal of Radio analytical and Nuclear Chemistry, Vol. 231, Nns /-2 (1998) 147-152 Gamma-spectrum of 241Am Abdulrahman Abdul-Hadi Chemistry Department, A.E.C.S, P.o. Box 6091 The γ-ray spectrum of 241Am from 80 to 850 keV was studied with a high resolution semiconductor γ-ray spectrometer; α-γ- and α-electron-coincidence spectra were studied with semiconductor and Americium-241 has been used as a portable source of both gamma rays and alpha particles for a number of medical and industrial uses.

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.

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.
