Welcome to the NASA/GSFC Radiation Effects & Analysis Home Page!
The Radiation Effects and Analysis Group (REAG) consists of a small core of civil servants aided by industrial support contractors.
The REAG performs testing & analysis investigating the effects of radiation on electronics &
photonics. A brief summary of these effects is available.
This Home Page is here for electronics designers, project managers, parts engineers,
other radiation groups, and anyone with an interest. Enjoy!
Testing has been performed on just about anything in the realm
of electronics & photonics. A searchable list of devices
that have been tested is available, as are device test reports. Please
have the courtesy to check the device list for
yourself, if you have questions about what has been tested. If you are interested in a collaboration, please contact
