Abstract: When irradiating an Advanced Micro Device (AMD) Processor that is connected to the motherboard within a chamber, it is important to shield the motherboard from the gamma rays. In doing so I constructed a collimator with lead (Pb) bricks so that only the AMD processor is open to the gamma rays. While the motherboard was powered, the AMD processor experienced radiation. The results examined the effects that radiation had on an AMD processor and whether or not the processor could survive in the harmful space radiation environment.
