$\epsilon =\sum {\epsilon}_{\text{in}}-\sum {\epsilon}_{\text{ex}}+\sum Q$

where Σ*ε*_{in} is the sum of the energies (excluding rest energies) of all directly and indirectly ionizing particles incident on the volume, Σ*ε*_{ex} is the sum of the energies (excluding rest energies) of all directly and indirectly ionizing particles emerging from the volume, and Σ*Q* is the sum of all changes (decreases: positive sign; increases: negative sign) of rest energy of nuclei and elementary particles in any transformations which occur in the volume
