17 Americium-241(Am) is an artificially produced radioactive isotope which was commonly used in smoke detectors. It decays through emission of an a-particle to neptunium (Np).(a)(i)Complete the nuclear equation which represents the decay of americium.(2)24195Am→Np+0*(ii) Explain why mos...
Studies have been carried out on removal of americium from the effluent generated during anion exchange purification of plutonium. Americium 241, generated by the beta decay of Plutonium-241, is the major source of 伪 activity in this highly acidic effluent and its removal would render the waste...
Also, a pyrochemical process would allow a speedy reprocessing which would eliminate the out of pile fuel inventory and reduce the 241Am build up due to 241Pu decay. [0005] There have been developed two pyrochemical processes for the separation of Pu-U from spent fuel by electrolysis in ...
1), where kH2O,Am is the experimentally determined luminescence decay constant for Am(III) in s− 1.95 The luminescence lifetimes of the Am(III) aqua ion were determined to be 24.6 ns in H2O and 162 ns in D2O. (1)NH2O,Am=2.56×10−7kH2O,Am−1.43 Photoexcitation of americium ...
Both long-lived isotopes decay by emission of α-particles: 241 Am with energies of 5.48 (85.2%) and 5.44 MeV (12.8%), and 243 Am with energies of 5.27 (88.1%) and 5.23 (11%) MeV. Only the isotopes 241 Am and 243 Am are applied in science and technology. Am metal is silvery ...
