Neutron Flux-Energy Spectral Characterization of a Deuterium-Tritium Neutron Generator at Oregon State University

Creator:: Eastman, Abigail L.
Abstract:: The neutron flux-energy spectral characterization of a Thermo Fisher MP320 deuterium-tritium neutron generator was performed for two shielding configurations, one with substantial moderator between the source and the sample and one without such moderator. The STAYSL PNNL spectral adjustment code was utilized in conjunction with MCNP modelled reference spectra and...

Effects of MCNP Model Resolution on Predicting Water Equivalent Thickness of Nanocomposite Materials in High-Energy Proton Fields

Creator:: Freilich, Justina A. M.
Abstract:: Manned missions beyond low-Earth orbit present tremendous, multifaceted radiological challenges. The deep space radiation environment contains high-energy protons and heavy ions, which are not sufficiently shielded by the aluminum alloys that have historically been used in spacecraft. To address these shielding concerns, polymer-based nanocomposites have been proposed. Radiation transport simulations...

Beehive model creation for use in determining radiation dose to beeswax and bee larvae

Creator:: Jia, Junwei
Abstract:: Honeybees and honey combs are good indicators of environmental contamination and can be important for dose calculations. In the event of reactor accidents and nuclear weapon testing, the released radioactive materials are likely to be transported through various environmental pathways as well as by humans and animals, including bees. Due...

Dosimetry Model for Alpha Emitters in a Radioactive Skin Patch for Treatment of Early-Stage Nonmelanoma Skin Cancers

Creator:: Squillante, Joyce
Abstract:: Nonmelanoma skin cancer (NMSC) is the most common malignancy in Caucasian populations. One existing treatment modality for NMSCs is external radiotherapy delivered to the skin cancer tumor by a beta-emitter-containing radioactive skin patch. Alpha emitters, with their higher linear energy transfer than beta particles and shorter range in tissue, make...
