The empirical characteristics of the environmental factors affecting the design, operation, calibration, testing, and on-line performance requirements of radiation sensors intended for operation in the interplanetary environment are surveyed. The environmental factors surveyed and discussed include ionizing electromagnetic radiation, corpuscular radiation of both solar and galactic origin, and meteoroids. The survey is limited to the radiations and meteoroids existing in the region outside of the earths magnetosphere. Where possible the survey is based on observations made with space probes located beyond the magnetosphere. Where data from deep space probes are not available, the characteristics of the environmental factors have been estimated from measurements made at or near the surface of the earth. Author
