Title: Calculations of Fluence Rates of Unscattered X- and Gamma-Ray Photons Emerging From Model Spheres of Special Nuclear Material
Published: November 30, 2009
Abstract: Calculations have been done to develop estimates of the fluence rate of unscattered x and gamma rays emerging from two model spheres of special nuclear material: one of uranium enriched to 93.5% by weight of U-235; one of plutonium enriched to 6.0% by weight of Pu-240.
