DOSE: Total Ionizing Dose
OverviewThe CREME96 DOSE program module evaluates the dose (in rads) from an input particle flux file. The DOSE program is primarily intended for evaluating the dose due to non-trapped components of the radiation environment (solar quiet fluxes and solar energetic particles.) The DOSE module can also be used to evaluate dose due to the trapped proton fluxes produced by the CREME96/TRP program module. However, in general, such calculations are not recommended. Although the DOSE trapped proton calculations are as accurate as the underlying AP8 models allow, the CREME96/TRP module does NOT include trapped electrons. Trapped electrons often provide a significant contribution to total ionizing dose, at least for devices deployed under less than ~300 mils (~2 g/cm2 Al) of shielding. Better software for calculating dose due to trapped radiation, including both electrons and protons, is available elsewhere. The DOSE calculation integrates over all arrival directions, covering 4-pi steradians. The calculation treats the input flux as isotropic or, equivalently, as an omnidirectional average. InputsTo run the DOSE program module, you must:
OutputsResults of the DOSE calculation will be recorded in the output file. You can download the output .dse file to your machine. The output file will contain the average dose rates in rads/sec and krad/year. Average dose rates are reported in rads/sec and krad/year. In addition, for the "worst-week" and "worst-day" solar particle environments, the event-integrated dose is also reported. The output file contains a header which documents the inputs to the calculation. This header also reproduces the header information from the particle flux file which you input to DOSE.
