This paper summarizes the results of radiation tests of cultured quartz resonators. The tests were conducted to determine the frequency shifts of the resonators as a result of high and low levels of proton and gamma irradiation. All resonators tested were 5 MHz, 5th overtone, AT cut units manufactured in different lots by Bliley Electric Company from nine bars of Premium-Q, swept, cultured quartz produced by Sawyer Research Products. Resonators manufactured from the same bar of cultured quartz showed consistent frequency changes when subjected to high level gamma radiation. However, this consistency did not exist when the resonators were exposed to low level gamma radiation. For low level radiation no apparent correlation exists between the aluminium content of a resonator and its radiation induced frequency shift. A correlation exists between the low level radiation induced frequency shift of a resonator and the manufacturing lot in which the resonator was produced.
