9.2.6 Planetary radiation environments

a. For Jupiter the model described in [RN.17] shall be used.

NOTE No standard is defined for the radiation environment at other planets but some information is available in Annex I.6.

b. For internal charging, potential enhancements in planetary radiation belts shall be included in the assessment.

NOTE Evidence from Galileo [RD.19] suggests that enhancements of fluxes in jovian orbit of between a factor 2 and 3 times that expected from the mean Divine and Garrett model, which is included in [RN.17] can take place [RD.20].
