Device shielding can help, but several factors must be considered. Shield geometry & analysis technique, shield material composition, and device composition are all relevant in predicting shield effectiveness. Electrons can be effectively attenuated by aluminum shielding even at high energies. However, while aluminum shielding is effective for low-energy protons, it is ineffective for the high-energy protons (>30 MeV).
A list of
parts that have been tested for TID since 1991 is available.
Reports are now available on line.
Total Dose Testing is performed at the Goddard Space Flight Center Radiation Effects Facility (GSFC REF).
Total
Dose testing at NASA/GSFC is handled by
Dr. Robert Reed. Please
contact him for further TID information, or contact
Ken Label if you have
a candidate new technology device.
