Engineering Nuclear Engineering Physics Cs-137 scattering dosimetry calibration radiation exposure ISO standard 4037 specifies that for calibrating protection level dosimeters, scattered radiation should contribute less than 5 percent of the exposure. In previous work, we reported the results of an MCNP analysis of the shadow shield technique that was performed for a calibration range with a Cs-137 irradiator. This thesis examines the energy distribution of the photons contributing to the exposure percent scatter (S%) and the detailed origin of the scatter that originates in the irradiator. In summary, it reports that: 1) the majority of S% is due to photons with energies that are significantly below the source energy, 2) a significant percentage of S% is due to photons that scatter within the source and source capsule walls, and 3) S% due to scatter within the irradiator is even more significant than we previously reported. 2011-09-27 English text The Ohio State University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=osu1313095840 http://rave.ohiolink.edu/etdc/view?acc_num=osu1313095840 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
