41. Measurements for the Development of Simulated Naturally Occurring Radioactive Materials
Series: Journal of Research (NIST JRES)
Report Number: 117.008r2012
Topic: Radiation Physics
Published: 4/3/2012
Author: Leticia S Pibida
Abstract: Nineteen different commercially available samples containing naturally occurring radioactive materials (NORM) (i.e., natural uranium, thorium, radium and potassium) were investigated, including zircon sand, cat litter, roofing tiles, ice melt and ...

42. Micelle size effect on Fe-55 Liquid Scintillation Efficiency
Topic: Radiation Physics
Published: 12/1/2013
Authors: Denis E Bergeron, Lizbeth Laureano-Perez
Abstract: We used efficiency tracing techniques to study the micelle size effect on liquid scintillation counting of the low-energy Auger electron emitter, 55Fe. We determined micelle hydrodynamic diameters for specific LS cocktails via dynamic light scatteri ...

43. Neutron Test Results of Preliminary Measurements and Calculations Using a Handheld Instrument
Series: Technical Note (NIST TN)
Report Number: 1788
Topic: Radiation Physics
Published: 3/18/2013
Authors: Leticia S Pibida, Craig Heimbach, Bruce R Norman, Alan K Thompson, Maynard S Dewey
Abstract: Initial neutron measurements and calculations were performed to investigate the response of handheld radionuclide identifiers (RIDs) to neutron sources with different moderators/scattering conditions

44. Optimal filtering, record length, and count rate in transition-edge-sensor microcalorimeters
Topic: Radiation Physics
Published: 12/16/2009
Authors: William Bertrand Doriese, Gene C Hilton, Kent D Irwin, Francis Joseph Schima, Joel Nathan Ullom, Joseph S. Adams, Caroline A. Kilbourne
Abstract: In typical algorithms for optimally filtering transition-edge-sensor-microcalorimeter pulses, the average value of a filtered pulse is set to zero. The achieved energy resolution of the detector then depends strongly on the chosen length of the pulse ...

45. Pinhole X -ray camera photos of an ECR ion source plasma
Topic: Radiation Physics
Published: 11/1/2011
Authors: Lawrence T Hudson, Sandor Biri, E Takacs, R. Racz, J. Palinkas
Abstract: A 70 micrometer pinhole and an X-ray CCD camera in single photon counting mode were used to obtain spatially and spectral resolved images of an electron cyclotron resonance (ECR) ion source generated plasma. The method has good spatial resolution as ...

46. Post-Irradiation Study of the Alanine Dosimeter
Series: Journal of Research (NIST JRES)
Topic: Radiation Physics
Published: 7/14/2014
Author: Marc F Desrosiers
Abstract: Post-irradiation stability of high-dose dosimeters has traditionally been an important measurement influence quantity. Though the exceptional stability of the alanine dosimeter response with time has rendered this factor a non-issue for routine work ...

47. Probing the Water Content in Polymer Electrolyte Fuel Cells Using Neutron Radiography
Topic: Radiation Physics
Published: 5/8/2012
Authors: Daniel S Hussey, Jeffrey Mishler, Yun Wang, Rangachary Mukundan, Jacob Spendelow, Rodney Borup
Abstract: This in-situ study examines the water content in polymer electrolyte fuel cells (PEFCs) using neutron radiography. Various conditions such as different polytetraflouroethylene (PTFE) loadings in the gas diffusion media including the micro-porous laye ...

48. Recommendations for Improving Consistency in the Radiation Fields used During Testing of Radiation Detection Instruments for Homeland Security Applications
Series: Journal of Research (NIST JRES)
Report Number: 118.014
Topic: Radiation Physics
Published: 5/28/2013
Authors: Matthew Merril Mille, Bruce R Norman, Leticia S Pibida
Abstract: Several measurements and calculations were performed to illustrate the differences that can be observed in the determination of exposure rate or ambient dose equivalent rate used for testing radiation detection systems against consensus standard. ...

49. Relationship between CTDI values and measured Peak Skin Dose (PSD)
Topic: Radiation Physics
Published: 7/16/2013
Authors: Ronaldo Minniti, Hugo de las Heras Gala, Sean Wilson, Chad Mitchell, Marlene Skopec, Claudia Brunner, Kish Chakrabarti
Abstract: In this work we relate the CT dose index volume (CTDIvol) readily displayed in all CT units with an actual Peak Skin Dose (PSD) value. Measurements of the CTDI and skin exposure were performed simultaneously using an ionization chamber and radiochrom ...

50. Reply to ,Comment on "Testing Three-body Quantum Electrodynamics with Trapped Ti20+ Ions: Evidence for a Z-Dependent Divergence between Experiment and Calculation"
Topic: Radiation Physics
Published: 4/12/2013
Authors: Lawrence T Hudson, C T Chantler, M N Kinnane, John D Gillaspy, A.T. Payne, L F Smale, Albert Henins, Joshua M Pomeroy, J A Kimpton, E Takacs, K Makonyi
Abstract: We find that Epp‰s [1] hypothesis - namely that the current experimental data set is well represented by a small constant or zero offset from the predictions of Artemyev et al. [2] - is not supported by standard statistical analysis. We find that add ...
