Dose Enhancement Effects in the Aerospace Corporation Co-60 Irradiator.
Abstract
The magnitude of the low energy component of the radiation energy spectrum inside The Aerospace Corporation Co-60 irradiator has been determined. Thermoluminescent detectors and a specialized ionization guage were used to verify the usefulness of a lead (0.06 ) and aluminum (0.03 ) sample shielding box to harden the Co-60 photon energy spectrum. The area of uniform dose as a function of distance from the Co-60 source inside the irradiator has also been determined. The results suggest two recommendations for use of the irradiator: The Pb/A1 box should be used for all irradiated samples where low energy radiation can be a factor, and samples should be placed as close to the source as possible, within the constraints of a homologous radiation field.
