A radiation-physics game for nuclear medicine students. Energy loss follows the Bethe formula, charged particles feel a screened Coulomb force, photons interact by Rayleigh, Compton (Klein–Nishina), photoelectric, pair and triplet production, and inner-shell vacancies relax by Kα fluorescence or Auger emission according to the fluorescence yield. The pump and steering are the only parts that are not physics.
Created by Poovendhan Mathiyazhagan, NMCalc.
Data: decay energies from evaluated nuclear data (NNDC/ENSDF); K-edge and Kα energies from NIST X-ray transition tables; calculated atomic radii (Clementi et al.). Game scales and densities are simplified for play.
