The susceptibility of quartz oscillators and atomic frequency standards to natural and enhanced ionizing and particle radiation is an important parameter in predicting the short- and long-term performance of these standards in spacecraft. Characterization of the response of frequency standards to ionizing and particle radiation should be based on a thorough understanding of the radiation environment (proton, electron, neutron, flash X-ray radiation, and single-event upset) and radiation scenarios (dose/anneal cycle, combined environments). A discussion of radiation environments (proton, electron, neutron, flash X ray, gamma, and single-event upset) is presented. Selection criteria for radiation sources, including dosimetry and procedures for the radiation testing of frequency standards, are discussed. By examining results of numerous previous studies, including radiation environments, this paper, which is a proposal for IEEE Standard Project P1193, provides direction for the methods by which the radiation sensitivity of frequency standards can be assessed.
