Some Geant4 physics models require cross section data files. The locations of these datasets is specified by environment variables.

No Format
G4LEVELGAMMADATA
G4RADIOACTIVEDATA
NeutronHPCrossSections
G4LEDATA
G4ELASTICDATA

The datasets can be obtained from the Geant4 downloads area.

Here is an example bash script for setting up these environment variables, assuming that the data files were downloaded and unpacked to the (fake) directory /path/to/data.
