41. The " McCluskey Room " was used to separate americium from plutonium during the Cold War. 42. This procedure is well known as nuclear transmutation, but it is still being developed for americium . 43. Another proposed space-related application of americium is a fuel for space ships with nuclear propulsion. 44. Plutonium, neptunium and americium form two basic oxides : An 2 O 3 and AnO 2. 45. Starting at uranium-238, isotopes of plutonium, americium , and curium are all produced. 46. Initial experiments yielded four americium isotopes : 241 Am, 242 Am, 239 Am and 238 Am. 47. The circle of darker metal in the center is americium -241; the surrounding casing is aluminium. 48. Neutron porosity logging tools contain an americium -beryllium neutron source, which irradiates the formation with neutrons. 49. Americium is commonly used in industry as both an alpha particle and low photon energy gamma radiation source.50. Americium -aluminium alloys can be formed by melting americium dioxide with aluminium and an additional fluxing agent.
