Abstract:

The effects of nuclear radiation on rubidium gas cell frequency standards and components are presented. including the results of recent tests where a continuously operating rubidium frequency standard Efratom, Model M-100 was subjected to simultaneous neutrongamma radiation. At the highest neutron fluence 7.5 x 1012 ncm2 and total dose 11 kradSi tested, the unit operated satisfactorily the total frequency change over the 2.5 hour test period due to all causes, including repeated retraction from and insertion into the reactor, was less than 1 x 1O-10, The effects of combined neutrongamma radiation on rubidium-frequency- standard physics-package components were also studied, and the results are presented.
