The spatial-scale dependence of the observed anisotropy of reflected and emitted radiation

Creator:: Ye, Qian
Abstract:: The Earth Radiation Budget Experiment (ERBE) uses Angular Dependence Models (ADMs) to convert satellite observed radiances to radiative fluxes at the top of the atmosphere. Owing to errors in scene identification and to the relationship between the spatial scales of cloud systems and the spatial resolution of the ERBE scanner,...

Simulating the dose enhancement effects of platinum nanoparticles in a spherical geometry with Monte Carlo calculations

Creator:: Mathews, Joshua A.
Abstract:: Background: The use of high-Z nanoparticles as radiation dose enhancers has been researched thoroughly over the past decade. High-Z nanoparticles introduced to a medium increase the probability of photoelectric absorption. This leads to an increase in the production of short range characteristic and Auger electrons and, thus, local radiation dose....

Implementation and evaluation of a participating media radiation model in the TEMPEST thermal-hydraulic computer code

Creator:: Rector, David R.
Abstract:: In this work, a method for solving the differential form of the radiative transfer equation was implemented into an existing three-dimensional thermal-hydraulic computer program known as TEMPEST. The method used was the P-l approximation, where the angular distribution of the radiation intensity is represented by a truncated series of spherical...

Radiation from an infinite plane to parallel rows of infinitely long tubes - hottel extended

Creator:: Qualey, Douglas L.
Abstract:: A two-dimensional model for predicting the rate of radiation heat transfer for the interior of an industrial furnace is described. The model is two-dimensional due to the assumptions of the heat source as an infinite radiating plane and the heat sink as rows of parallel tubes that are both infinite...

A model for the mechanical behavior of irradiated mixed carbide sphere pac fuel pins

Creator:: George, Thomas L.
Abstract:: A model is developed that allows the prediction of the stress-strain distribution in a mixed carbide sphere pac fuel pin during irradiation. The model is coupled with a previously developed model for the thermal behavior of the pin. The one-dimensional (radial at various axial locations) solution is for quasi-steady pin...

Hybrid classical-quantum dose computation method for radiation therapy treatment planning

Creator:: Colburn, Gabriel G.
Abstract:: Radiation therapy treatment planning and optimization requires accurate, precise, and fast computation of absorbed dose to all critical and target volumes in a patient. A new method for speeding up the computational costs of Monte Carlo dose calculations is described that employs a hybrid classical-quantum computing architecture. Representative results are...

Modeled and observed longwave radiances at the top of the atmosphere

Creator:: Stone, Kenneth A.
Abstract:: One method of estimating the longwave radiative heating of the atmosphere is to combine satellite observations of emitted radiances with those computed from synoptic temperature and humidity profiles. Modeled and observed radiances are brought into agreement by altering cloud properties or even by adjusting the temperature and water vapor profiles....

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...

Experimental simulations of a rotating bubble membrane radiator for space nuclear power systems

Creator:: Al-Baroudi, Homan Mohammed-Zahid
Abstract:: A rotating, flat plate condensation experiment has been developed to investigate the heat of the Rotating Bubble Membrane Radiator (RBMR). The RBMR is a proposed heat rejection system for space applications which uses working fluid condensation on the inside surface of a rotating sphere to reject heat to space. The...

A comparison of deterministic and probabilistic radiation dose assessments at three fictitious ¹³⁷Cs contaminated sites in California, Colorado, and Florida

Creator:: Brock, Terry A.
Abstract:: Two methods of radiation dose assessment were evaluated for the Cs-137 in soil ⇒ leafy vegetable ⇒ human consumption exposure pathway at three fictitious contaminated sites in California, Colorado, and Florida. An annual dose equation was developed and per USEPA risk assessment guidelines, traditional, single point annual dose estimates were...
