Estimation of absorbed radiation doses to skin and S-values for organs at risk due to nasal administration of PET agents using Monte Carlo simulations
Autor: Eero Hippeläinen, David M. Hamby, Colby D. Mangini, Nisha Singh, David Boozer, Jim O'Doherty
Publikováno v: Physica Medica. 84:301-302
Purpose The intranasal (IN) administration of radiopharmaceuticals is of interest in being a viable route for the delivery of radiopharmaceuticals that do not ordinarily cross the blood-brain barrier (BBB). However, to be viable in a patient populati

Building protection- and building shielding-factors for environmental exposure to radionuclides and monoenergetic photon emissions
Autor: David M. Hamby, E D Dickson
Publikováno v: Journal of Radiological Protection. 36:579-615
We describe a simplified method for calculating both building protection- and shielding-factors for generic one- and two-story housing-unit models that are source-term dependent. Typically, radionuclide-independent factors are applied generically to

Model-based pulse deconvolution method for NaI(Tl) detectors
Autor: Haori Yang, Abi T. Farsoni, David M. Hamby, Wuyun Xiao
Publikováno v: Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment. 769:5-8
To overcome the long-standing problem of pulse pile-up in radiation detection with scintillation detectors, a direct pulse deconvolution method is put forward based on a newly developed convolution model. By removing all the exponential tails that co

The Effect of Cognitive Load on Decision Making with Graphically Displayed Uncertainty Information
Autor: Kevin A. Makinson, John A. Edwards, Pamela M. Allen, David M. Hamby, Frank Snyder
Publikováno v: Risk Analysis. 34:1495-1505
An experiment examined the ability of five graphical displays to communicate uncertainty information when end users were under cognitive load (i.e., remembering an eight-digit number). The extent to which people could accurately derive information fr

A Review of Contemporary Methods for the Presentation of Scientific Uncertainty
Autor: Kevin A. Makinson, David M. Hamby, J. A. Edwards
Publikováno v: Health Physics. 103:714-731
Graphic methods for displaying uncertainty are often the most concise and informative way to communicate abstract concepts. Presentation methods currently in use for the display and interpretation of scientific uncertainty are reviewed. Numerous subj

The new VARSKIN 4 photon skin dosimetry model
Autor: Stephanie P. Bush-Goddard, Jarvis Caffrey, C. J. Lodwick, Mohammad S Saba, Sami Sherbini, S. R. Reese, Todd S. Palmer, David M. Hamby, Kathryn A. Higley
Publikováno v: Radiation Protection Dosimetry. 154:356-363
A new photon skin dosimetry model, described here, was developed as the basis for the enhanced VARSKIN 4 thin tissue dosimetry code. The model employs a point-kernel method that accounts for charged particle build-up, photon attenuation and off-axis

Decision Making for Risk Management: A Comparison of Graphical Methods for Presenting Quantitative Uncertainty
Autor: Pamela M. Allen, David M. Hamby, Frank Snyder, John A. Edwards, Kevin A. Makinson
Publikováno v: Risk Analysis. 32:2055-2070
Previous research has shown that people err when making decisions aided by probability information. Surprisingly, there has been little exploration into the accuracy of decisions made based on many commonly used probabilistic display methods. Two exp

A review of instruments and methods for dosimetry in space
Autor: David M. Hamby, Jarvis Caffrey
Publikováno v: Advances in Space Research. 47:563-574
Instruments and methods recently used for space radiation dosimetry are reviewed for the purposes of comparison and reference. Passive detection methods mentioned include track-etch, luminescent, nuclear emulsion, and metal foil detectors. These can
