- The mass on a particle is reduced using the time constant approach
- The decay constant is defined by the half-life
- Doses are computed from published conversion factors by radionuclide
- There are limitations to this simple approach:
- Decay does not start until the particle is emitted
- For continuous emissions, the emission rate must be decay corrected
- Concentration and deposition are decayed during the calculation
- Concentration and deposition are NOT decayed after file output
