241Am decays to an isotope of neptunium (237Np), emitting an alpha particle with an energy of approximately 5.5 MeV and gamma rays, with the majority having an energy of 60 keV. 237 Np has a half-life of 2.14 million ionizing energy to living cells. Gamma radiation: high-energy electromagnetic radiation emitted by certain radionuclides when their nuclei transition from a higher to a lower energy state. These rays have high energy and a short wave length.

The MOX (UO2&PuO2) caramel fuel mixed with 241Am, 242mAm and 243Am as burnable absorber actinides was proposed as a fuel of the MTR-22MW reactor. 2015-04-01 1999-12-01 Due to different energy spectra of the 241Am-Be and 252Cf sources, integrated efficiency of the 125 mm diameter NE213 detector for the two sources shows bias dependence.

In this study, a conventional Bonner sphere spectrometer, together with 6LiI(Eu) inorganic scintillator used as the central detector, was used to obtain the neutron energy spectrum of an 241Am 6. Collect the 241Am alpha spectrum until the peak height is at least 1000 counts.

237 Np has a half-life of 2.14 million ionizing energy to living cells. Gamma radiation: high-energy electromagnetic radiation emitted by certain radionuclides when their nuclei transition from a higher to a lower energy state. These rays have high energy and a short wave length. Gamma rays penetrate tissue farther than do beta or alpha particles, but leave a lower concentration of The neutron energy distribution of the IRSN standard 241 Am–Be (α,n) source was measured using a proton recoil liquid scintillator, BC501A, >1.65 MeV. The experimental data were compared with the ISO recommended neutron energy distribution for an Am–Be source and some significant discrepancies were observed.
