Energy 1 (or range): ± / - keV Energy 2 (or range): ± / - keV Energy 3 As regards gamma-ray fluxes, the contribution at 60 keV energy, associated with the decay of 241Am, and the one at 2.2 MeV, due to the radiative capture of neutrons in the biological shield (water) was determined (for difference) with use of bare and lead shielded TLD700 dosimeters. We report the total (coherent + incoherent) scattering cross sections of some lead and sodium compounds measured at angles less than 10° for ²⁴¹Am (59.54 keV) gamma rays. The experimental cross sections so obtained are compared with the data interpolated from theoretical compilations based on nonrelativistic Hartree-Fock (NRHF) model for the samples of interest. In the Gamma decay may also follow nuclear reactions such as neutron capture, nuclear fission, or nuclear fusion.

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

Half-Life: (157850 ± 240) d [2] 241Am has been widely used as a low energy standardized gamma ray and X-ray source for energy and efficiency calibrations. However in the most cases, only three L X-ray Lα, Lβ, Lγ lines were listed. Using a high resolution Si (Li) detector with the help of computer program for spectrum analyzing, we have decomposed these lines into its components.

The With the high resolution of microcalorimeter detectors, previously unresolvable gamma-ray lines are now clearly resolvable. A careful measurement of 241Am decay with a large microcalorimeter array has yielded never before seen or predicted gamma lines at 207.72 +/- 0.02 keV and 208.21 +/- 0.01 keV. These have been made possible because of new microwave-multiplexing readout and improved In this paper results of X-ray and gamma-ray emission probabilities per decay of (51)Cr and (241)Am are presented. The measurements were carried out by means of HPGe planar and REGe spectrometers.

The decay of 241Pu is shown in Figure 8.1. Because of the long half-life of 241Am, the concentration of the 241Am daughter continues to increase for up to 75 yr. Aged plutonium samples often have very high 241Am content, especially if the initial 241Pu concentration was high. 221 The decay scheme of Am²⁴¹ is discussed in terms of new information on the conversion electrons, gamma rays, and L series x-rays accompanying its alpha decay.

It poses a more significant risk if ingested ( The radiation from the decay of americium-241 and its daughters is in the form of alpha particles, beta particles, and gamma rays. Alpha particles can travel only 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 decayed into americium-241 through a process known as beta decay. 241Pu was once found naturally and decayed to form a natural supply of 241Am.
