4 Oscillators for Space Rditi Radiation Levels Total Dose of 3 krad (Si) (LEO) to 100 krad (Si) (GEO) Use of suitable radiation resistant add on components such as semi conductors from ESA or NASA (or equivalent) t)qpl or QML lists or other approved sources. Upscreening if necessary Use of swept quartz material for the quartz resonators Sweeping is a purification process that removes certain impurities and thereby improves the radiation sensitivity of quartz crystals. 4
