1. New National Air-Kerma Standard for Low-Energy Electronic Brachytherapy Sources
Series: Journal of Research (NIST JRES)
Report Number: 119.022
Published: 10/6/2014
Authors: Stephen Michael Seltzer, C Michelle O\'Brien, Michael G Mitch
Abstract: The purpose of this report is to document the NIST air-kerma measurement standard for the electronic brachytherapy sources, i.e., the Axxent sources of Xoft, Inc., which operate at tube potentials of 50 kV and anode currents of 300 μA. The ...

Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 7887
Published: 10/16/2012
Author: Stephen Michael Seltzer
Abstract: This report details analyses in the development of certain correction factors for free-air ionization chambers used by the National Institute of Standards and Technology to realize air kerma for its measurement standards and calibrations of W-anode x ...

3. Measurements and Standards for Bulk-Explosive Detection
Published: 5/31/2012
Authors: Lawrence T Hudson, Fred B Bateman, Paul Mark Bergstrom, Frank Cerra, Jack Leigh Glover, Ronaldo Minniti, Stephen Michael Seltzer, Ronald E Tosh
Abstract: Due to the ease of assembly and leveraged disruptive effect, the improvised explosive device (IED) is the method of choice of today‰s terrorist. With more than ten thousand IED incidents annually, and global expenditures for aviation and commercial s ...

4. Absolute measurements of x-ray backlighter sources at energies above 10 keVa)
Published: 2/1/2012
Authors: Lawrence T Hudson, B.R. Maddox, H.S. Parks, B A Remington, C. Chen, S Chen, S. T. Prisbrey, A. Comley, C A Back, C. Szabo, John F Seely, Uri Feldman, Stephen Michael Seltzer, M. J. Haugh, Z. Ali
Abstract: Line emission and broadband x-ray sources with x-ray energies above 10 keV have been investigated using a range of calibrated x-ray detectors for use as x-ray backlighters in high energy density (HED) experiments. The conversion efficiency of short- ...

5. Efficiency calibrations of cylindrically bent transmission crystals in the 20 keV to 80 keV x-ray range
Published: 4/15/2011
Authors: Lawrence T Hudson, C Michelle O\'Brien, Uri Feldman, Stephen M. Seltzer, Hye-Sook Park, John F Seely
Abstract: Two quartz (10-11) crystals were cylindrically bent to 25.4 cm radius of curvature and were mounted in identical Cauchois type transmission spectrometers, and the crystal diffraction efficiencies were measured to 5 % absolute accuracy using narrow ba ...

6. Calculations of Fluence Rates of Unscattered X- and Gamma-Ray Photons Emerging From Model Spheres of Special Nuclear Material
Series: NIST Interagency/Internal Report (NISTIR)
Published: 11/30/2009
Author: Stephen Michael Seltzer
Abstract: Calculations have been done to develop estimates of the fluence rate of unscattered x and gamma rays emerging from two model spheres of special nuclear material: one of uranium enriched to 93.5% by weight of U-235; one of plutonium enriched to 6.0% b ...

7. Fifty years of AAPM Involvement in Radiation Dosimetry
Published: 4/30/2008
Authors: Geoffrey S Ibbott, C-M Ma, D W O Rogers, Stephen Michael Seltzer, J Williamson
Abstract: This paper reviews the involvement of the AAPM in various aspects of radiation dosimetry over its fifty year history, emphasizing the especially important role that external beam dosimetry played in the early formation of the organization. Topics co ...
