Abstract
Packaged commercial 434 MHz quartz SAW resonators were placed at the output of a Colbalt 60 source and exposed to gamma radiation of up to 50 Mrads. Additional devices were positioned in close proximity to the enriched uranium core of a nuclear reactor and exposed to intense neutron radiation of 4.5 x 1012 neutrons/cm2s for up to 40 seconds. The irradiated resonators were then inserted in the feedback loop of a custom oscillator to measure the shift in output frequency as a function of radiation exposure. No clear relationships were observed between the amount of radiation exposure and frequency shift in either case.
封装的商用434 MHz石英SAW谐振器放置在钴60源的输出端，并暴露在高达50毫瓦的伽马辐射中。另外的装置被放置在一个核反应堆的浓缩铀堆芯附近，并暴露在4.5 x 1012中子/厘米秒的强烈中子辐射下长达40秒。然后将辐照谐振器插入定制振荡器的反馈回路中，以测量作为辐射暴露函数的输出频率的移位。在这两种情况下，没有观察到辐射量与频率移动之间的明确关系。
