The Effects of Radiation on Science Instruments during Grand Tour Type Missions

A discussion is presented of the extent of radiation effects encountered with radiation source models and the status of protection techniques for representative science instruments proposed for the Outer Planets Grand Tour missions. Preliminary results of a literature search to collect damage/interference effects data on sensitive components such as silicon detectors and vidicon tubes are described along with results from the various experimenters whose instruments have been used as models in previous studies.
