The effect of radiation on the IRAS all-sky surveyThe Infrared Astronomical Satellite (IRAS) is in a sun synchronous, 'near' polar orbit at an altitude of 900 km. The primary objective of IRAS is related to the conduction of an all-sky survey in the wavelength range from 8 microns to 120 microns. The present investigation is concerned with three components of the radiation environment encountered by IRAS, taking into account the high energy protons in the South Atlantic Anomaly, high energy electrons in the horns of the Van Allen belts, and cosmic rays. The effect of radiation on the returned data stream is studied, and attention is given to the steps which were taken to minimize the impact of radiation on the completeness of the survey.
