Thermal conductivity was calculated from measured density at room temperature, literature values of heat capacity and thermal diffusivity measured by laser flash method in vacuum. Thermal conductivity of americium-containing barium plutonate was roughly independent of temperature and registered almost the ...

The isotope239Pu produced in appreciable amounts in nu-clear reactors is of major importance, because of its largefission cross section with thermal neutrons. It was namedafter the planet Pluto in analogy to U and Np.2.3 Americium (Am) and curium (Cm)Element 95, americium (Am), and ...

For neutron radiation, radiation sources can either be a plutonium–beryllium source (Pu–Be) or a americium–beryllium source (Am–Be). Pu–Be emits energy of 3.92 and 4.43 MeV, while Am–Be emits about 4.5 MeV [110,160]. As neutrons have no charge, their detection is performed ...
