Am 241 Decay Chain - Sticky Bytes

Recognising isotopes by the shape of their spectra is an art and takes practice, which is why we are building this database of spectra. Americium-241 is also suitable for calibration of gamma-ray spectrometers in the low-energy range, since its spectrum consists of nearly a single peak and negligible Compton continuum (at least three orders of magnitude lower intensity). Medicine. Gamma rays from americium-241 have been used to provide passive diagnosis of thyroid function. 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 The neutron energy spectrum of an 241Am-Li radionuclide source has been measured in a low scatter room at the National Physical Laboratory, using a variety of spectrometers namely: a Bonner sphere The neutron energy spectrum of a 241Am-Be(_,n) source was measured by means of a 3He spectrometer in the energy range from 100 keV to 11 MeV.

Gamma ray spectra of strong 241Am sources may reveal information about the source composition as there may be other radioactive nuclides such as progeny and radioactive impurities present.

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. Similar examples are given for each of the spectral In order to practically use this spectrometer, it is necessary to calibrate this system using standard neutron sources. This research aimed to determine the calibration factor of Bonner spheres spectrometry system and energy spectrum of two standard 241Am-Be and 252Cf sources in the atomic energy organization.

In this work the possibility to use gamma spectrometry to identify inherent signatures in 241Am sources in order to differentiate sources from each other, is investigated. 10.1093/rpd/nct238 - High-resolution neutron energy spectra, covering the entire energy range of interest, for two standard radionuclide neutron sources (241Am-B and 241Am-F) have been derived from Bonner sphere measurements by using high-resolution a priori data in the unfolding process. In each case, two a priori spectra were used, one from a two-stage calculation and also one from a 2004-08-01 The 239PuBe neutron spectrum was measured in an open environment, while the 241AmBe neutron spectrum was measured in a closed environment. Gamma-ray spectra were measured using a NaI(Tl) scintillator using the same experimental conditions for both sources.
