- •
Fluorescence of atmospheric N2 has been implemented into the Geant4 framework.
- •
Model is used to predict fluorescent yield of alpha and beta particles.
- •
Model compared against existing experimental data and strong agreement is found.
- •
Fluorescent yield of alpha radiation found to scale with energy as a power law.
- •
Results suggest air fluorescence is applicable to localising radioactive sources.
