a. Experimental data from irradiations shall be used to validate prediction techniques.
b. If experimental data are used in place of elements of the prediction process, the parameter-space covered by experiment shall ensure that the data can be interpolated to operational environment conditions within the error limits specified by the project.
NOTE 1 This is especially important in assessing the response of the instrument to the local radiation environment.
NOTE 2 Examples of parameter space covered by the experiment are incident particle species and energy, angle of incidence, flux (to allow for effects of pulse pile-up).
