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 set, a 3He ionisation chamber, and a set of hydrogen recoil proportional counters. Calculations with the MCNP transport code have been used to explain some of the features seen in the spectrum.

Features in a gamma-ray spectrum So, when we look at the spectrum of a typical gamma-ray source, such as Cs-137, what should we expect to see? If we had a PERFECT instrument, we might expect to see a spectrum like this: since Cs-137 produces gamma rays with energies of 32.06, 36.40 and 661.7 keV. But what we ACTUALLY see looks quite different:

Half-Life: (8145 ± 80) d Ochi Spectrum λ Γ λ narrower, λ determines the width of the spectrum (x) = the gamma function of x Ochi spectrum is an extension of the BS spectrum, allowing to make it wider, small, for developing seas, or larger, for swell.

The results imply the need for dirty DU and NU samples that the MGA method should utilize the higher energy gamma-rays (up to 1001 keV of (234m)Pa) combined with lower energies of the spectra, which may be collected in a two detector mode (a planar Ge and a high efficient coaxial Ge).

Full Record; Other Related Research 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 set, a 3He ionisation chamber, and a set of hydrogen recoil proportional counters. Rad Pro Calculator online performs many nuclear calculations that are useful to the health physicist, radiological researcher, radiochemist, radiation safety officer, health physics technician (HP) and other professionals in radiation physics and radiological engineering. Following recent measurements [1,2] of the neutron and photon spectra of two different 241Am Li(a,n)10B source, this paper preliminarily reports on a method based on Monte Carlo simulation in order to obtain the pure and unperturbed 241Am-Li spectrum, hereafter called ideal, one that started within the source material, using the neutron spectrum measured outside the source encapsulations.

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

Applications of the data im gamma scintillation spectrometry are discussed. (C.H.) 2004-8-1 The spectrum acquisitioned for the 241Am active lung set for 50 000s with the torso plate and detector upon the lungs is as shown in figure 2. Although the detector covers the maximum area of the target organ, the photons from the adjacent organs containing activity may also be recorded at the detector, leading to an overestimation of organ The analysis of γ-ray spectra can be an arduous task, especially in the case of room temperature semiconductor detectors, where several distortions and instrumental artifacts conceal the true spectral shape. We developed a genetic algorithm to perform the unfolding of γ-spectra in order to restore the true energy distribution of the incoming radiation. We successfully validated our The results imply the need for dirty DU and NU samples that the MGA method should utilize the higher energy gamma-rays (up to 1001 keV of (234m)Pa) combined with lower energies of the spectra, which may be collected in a two detector mode (a planar Ge and a high efficient coaxial Ge). 2013-9-22 · The gamma spectrum of 241Am, 137Cs and 60Co were measured in different time periods by NaI(Tl) detectors. Results: The non-parametric Bootstrap method was used to process the gamma spectra measured in short time and the results were compared with the gamma spectra data measured in long time under the same conditions, and the calculated spectra agreed well with the measured spectra. 2007-5-17 Amptek manufactures X-ray detectors using both Si-PIN and CdTe sensors, each of which has advantages in certain applications.
