REPORT ON RADIATION-EFFECTS STATE OF THE ART 1962-1963

Generalized conclusions related to radiation effects on various materials, components, and systems include: (1) more experimental effort is still needed in studying combined effects of radiation and other environments. Of particular interest are the combination of radiation, extreme temperatures, and ultrahigh vacuum. In the ultrahigh-vacuum area the main interest should be concentrated on organic-materials. Although much is known concerning the loss of material due to evaporation and sublimation, very little is known concerning the effects of these material losses on the physical strength and electrical characteristics; (2) More research effort should be devoted to developing means for shielding ma terials, devices, and systems with known sus ceptibilities to radiation damage as a parallel effort, with research being conducted to increase resistance to radiation damage; and (3) More information is needed concerning the effects of space radiations on materials, devices, and com ponents.
