National Research Nuclear University MEPhI (Moscow Engineering Physics Institute), Moscow, Russia aut Dose Factors for Photon Accumulation in Uranium Oxides and Hexafluoride [Elektronische Daten] [V. Sakharov] The first results of a calculation of the dose factors of photon accumulation in uranium oxide UO2, triuranium octoxide U3O8, and uranium hexafluoride UF6 for a point isotropic monoenergetic source of photons with energy from 0.01 to 5 MeV for material thickness ranging from 0.5 to 25 μd are presented. The calculations are performed in infinite and barrier geometry taking account of all interactions of photons with matter. The possibilities of determining the accumulation factors of these mixtures on the basis of the accumulation factors of the individual elements are examined. Corrections for the barrier effect of the material are determined; it is noted that they are independent of the thickness, material, and energy of the source photons. The information obtained will make it possible to lower the computational error of the radiation dose when working with these materials, which are widely used in the nuclear fuel cycle.
