  2. Gamma Decay: 23994Pu 23994Pu +  Nucleus has energy levels Energy of transition emitted as a high energy photon Usually after a beta or alpha decay Many energies possible Stopped by meters of lead Used for food irradiation TOC

  3. Gamma ray energies released after Bi-212 Alpha decays

  4. Whiteboards: Gamma Decay 1 | 2 TOC

  5. 23994Pu --> 23994Pu +  239.054238 --> 239.052157 What is the energy of the gamma emitted? Parent mass = 239.054238 u Product mass = 239.052157 u Mass defect = parent - products = 0.002081 u Energy of radiation = (0.002081u)(931.5 MeV/u) = 1.94 MeV W 1.94 MeV

  6. 24596Cm --> 24596Cm +  ???.?????? --> 245.065484 What is the excited mass of the parent, if a 3.92 MeV gamma photon is emitted? Mass of 3.92 MeV = (3.92 MeV)/(931.5 MeV/u) = 0.004208266 u Excited parent is more massive than this by that amount Parent mass = 245.065484 + .004208266 u = 245.069692 u W 245.069692
