1996:70 Risks from Nuclear Waste


Partitioning and Transmutation – Annual Report 2010 - SKB

An alpha particle has two protons and two neutrons. Thus charge is +2. Alpha radiation diverted towards negatively charged plate. Alpha particle (α) and has same composition as helium nucleolus and is designated as H 2 4 e.

Then, the mass number of the new nuclide formed will be 241 - 4 = 237. The complete equation is: 95Am241 ---> 93Np237 + 2alfa4. Alpha particles are very heavy and cannot travel very far. They can be shielded by a layer as thin as a layer of dead skin cells. Ionization smoke detectors have a small americium source encased in a layer of foil and ceramic, which stops the alpha particles from traveling outside of the smoke detector. A smoke detector containing an americium-241 ionization chamber accumulates a significant amount of neptunium-237 as its americium decays; the following elements are also present in it, at least transiently, as decay products of the neptunium: actinium, astatine, bismuth, francium, lead, polonium, protactinium, radium, thallium, thorium and
