Abstract

The results of the testing of 4 MHz, 10.24 MHz and 10.95 MHz 3rd overtone SC-cut quartz crystals confirms earlier work on 5^th overtone AT-Cut, SC-Cut crystals. The testing showed that low dose rate radiation sensitivity is manufacturing lot dependent. Frequency variations due to low dose rate proton and gamma ray exposures varied between <1×10^-11 and 4×10^-10 per Rad. The majority of the crystals exhibited radiation sensitivities of 3-5×10^-11 per Rad. The hypothesis that a nonlinear relationship exists between low dose rate and high total dose rate was confirmed. Testing indicated that the majority of crystals exhibited a conditioning effect during successive exposures to low dose radiation
