befound. Gammaradiation is due to deceleration of incident particle radiation and
can be simulated experimentally by gamma rays by making use of a cobalt-60 source.
Depending on the orbit, the doses can reach a value of up to 100 krad of gamma
irradiation and up to 10

be noted that 1 rad corresponds to 10 mJ of energy absorbed by 1kg of material. For
planetary missions, the accumulated proton exposure might be higher and reach up
