The low-energy electron spectrum from the alpha-decay of 241Am has been analysed in the region of 2.5 - 22.5 keV at the 20 eV instrumental resolution using a combined electrostatic spectrometer 2016-03-11 The pure and unperturbed (ideal, at birth) spectra of 241AmLi (alpha,n)10B sources were determined using Monte Carlo simulations, along with the neutron spectrum measured outside a source’s encapsulation. Various parameters that affect photon and neutron yields and energy distributions were investigated. The source’s microparticle size was deduced. 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.
The misidentified -rays are not associated with the decay of 241Am, but rather are prompt -rays from alpha-induced reactions The γ-ray spectrum of 241Am from 80 to 850 keV was studied with

2016-03-11 · The alpha-spectrum of an open 241Am-emitter is measured with a semiconductor a-detector. In connection with a multi channel analyzer the main parts of the spectrum are investigated. Tasks. The spectrum of an uncovered 241Am-emitter is recorded with the multi channel analyzer. The energies of the two peaks preceding the principal peak are
Energy.
Once in the body, it tends to concentrate in the bone, liver, and muscle. Abstract: The pure and unperturbed (ideal, at birth) spectra of 241AmLi (alpha,n)10B sources were determined using Monte Carlo simulations, along with the neutron spectrum measured outside a source’s encapsulation. Various parameters that affect photon and neutron yields and energy distributions were investigated.
