Advancements in Phytoremediation, Dosimetry, and Environmental Radiological Protection: Integrating Endemic Plants, Anatomically Accurate Phantoms, and Real-world Data for Improved Assessments

Creator:: Hargraves, Joshua T.
Abstract:: The environmental impact of the nuclear industry has prompted the need for innovative remediation strategies and accurate radiological assessments. This paper synthesizes three studies that collectively explore the potential of endemic plant species for phytoremediation, the development of anatomically accurate phantoms for precise dosimetry calculations, and the critical evaluation of...

Exploring Novel Contrast Agents with Anthropomorphic Mesh Models in MCNP

Creator:: Garcia, Jacqueline K.
Abstract:: Breast cancer is the leading cancer in women with an estimated 13% of women in the United States developing a form of invasive breast cancer in her lifetime. The survival rate is estimated to be 85%, but the American Cancer Society estimates that early detection of breast cancer in the...

Cherenkov Glass Detectors for Gamma and Neutron Detection

Creator:: Natto, Hattan
Abstract:: Cherenkov detectors have been developed and used in several fields since the discovery of Cherenkov radiation. They do have several advantages compared with other detector types, such as low noise due to the low-energy threshold of Cherenkov radiation, and short decay constant (on the order of picoseconds). However, the light...

Understanding the Application and Benefits of Learning-based Methods in Nuclear Science and Engineering

Creator:: Gómez Fernández, Mario Enrique
Abstract:: Known as the fourth industrial revolution, digitization is an ongoing trend in all ﬁelds, in which various industries are integrating information technologies to support and improve their businesses. Nuclear technology industries have also increased their interest in data-driven methods by leveraging the potential of pattern recognition to identify anomalies and...

A Deterministic Photon and Electron Dosimetry Model for the Lens of the Eye

Creator:: Boozer, David L.
Abstract:: The lens dose equivalent (LDE) is a regulatory limit set to protect radiation workers. Current methods for estimating the LDE are specific to beam sources in a vacuum and require interpolating data from tables. A new set of deterministic equations for photon and electron point sources has been developed. These...

Special Nuclear Material Classification and Mass Content Estimation Using Temporal Gamma-Ray Spectroscopy and Machine Learning Methods

Creator:: Curtis, Jessica R.
Abstract:: Improving the methods used for the detection and estimation of fissile material mass content is essential to nuclear security and safeguards to ensure special nuclear material (SNM) accountability, control, safety and security. With the continued expansion of the nuclear industry and the need for safe management of spent fuel, improving...

Modeling of an Urban Radiocesium Pathway from Catchment to Wastewater Treatment Sludge

Creator:: Ng, George M. H.
Abstract:: The urban hydrology and hydraulics program, US EPA SWMM 5, has been coupled with a compartment model of a wastewater treatment plant (WWTP) in the system dynamics software, STELLA, to simulate the radiocesium pathway from urban catchment to the wastewater treatment sludge. Two literature case studies were re-examined. Firstly, a...

Faster, Sharper and Open: A New Pipeline for Biota Phantom Creation

Creator:: Neville, Delvan
Abstract:: Anatomically correct biota phantom creation has suffered from three primary weaknesses: the models take considerable time to make, are limited in detail by voxel size, and are created and simulated using proprietary software. Presented are trial runs of a new biota creation pipeline, FSOPhantom, that addresses these issues by creating...

Pine Tree Dosimetry: Development of Geometric and Compositionally Specific Sectional Models for Organ Dose Assessment

Creator:: Condon, Caitlin A.
Abstract:: Ideally, dosimetric models for pine trees will accurately reflect the doses to its critical organs. However, existing models (e.g. that in ICRP 108) for the pine tree are over simplified or solely focused on estimating doses to one specific organ, and none of the existing models attempt dosimetry to the...

Investigation of f-Element Extraction and Ligand Association in the ALSEP Extraction System for Used Nuclear Fuel Reprocessing

Creator:: Holfeltz, Vanessa E.
Abstract:: Effective separation of lanthanides (Ln) from the minor actinides (MA) is a crucial technical challenge to closing the nuclear fuel cycle. This separation is a necessary prerequisite to transmute long-lived isotopes of Am and Cm, which will allow a reduction of the repository volume, thermal load, and radiological toxicity of...
