1. 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 ...

2. A New NIST Primary Standardization of 18F
Topic: Radiation Physics
Published: 2/1/2014
Authors: Ryan P Fitzgerald, Brian Edward Zimmerman, Denis E Bergeron, Jeffrey T Cessna, Leticia S Pibida, Denise S Moreira
Abstract: A new primary standardization of 18F by NIST is reported. The standard is based on live-timed beta- gamma anticoincidence counting with confirmatory measurements by three other methods: (i) liquid scintillation (LS) counting using CIEMAT/NIST 3H e ...

3. Measurement Traceability in Medical Physics
Topic: Radiation Physics
Published: 1/1/2014
Author: Lisa R Karam
Abstract: Medical physics, the joining of physics with healthcare, requires a level of quality assurance beyond many applications of the physical sciences. Always the health, and often the life, of the patient depends on the precise and accurate implementation ...

4. The Importance of Dosimetry Standardization in Radiobiology
Series: Journal of Research (NIST JRES)
Topic: Radiation Physics
Published: 12/30/2013
Authors: Marc F Desrosiers, Larry A DeWerd, James Deye, Patricia Lindsay, Mark K. Murphy, Michael G Mitch, Francesca Macchiarini, Strahinja Stojadinovic, Helen Stone
Abstract: Radiation dose is central too much of radiobiological research. Precision and accuracy of dose measurements and reporting of the measurement details should be sufficient to allow the work to be interpreted and repeated and to allow valid comparisons ...

5. Improved Determination of the Neutron Lifetime
Topic: Radiation Physics
Published: 12/2/2013
Authors: Jeffrey S Nico, A. T. Yue, Maynard S Dewey, David McLarty Gilliam, G L. Greene, A. Laptev, W M. Snow, F. E Wiefeldt
Abstract: The most precise determination of the neutron lifetime using the beam method was completed in 2005 and reported a result of tau_n = (886.3 ± 1.2 [stat] ± 3.2 [sys]) s. The dominant uncertainties were attributed to the absolute determination of the f ...

6. 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 ...

7. High-resolution K-shell spectra from laser excited molybdenum plasma
Topic: Radiation Physics
Published: 11/1/2013
Authors: Lawrence T Hudson, C.I Szabo, P Indelicatio, John F Seely, T Ma
Abstract: X-ray spectra from Molybdenum plasmas were recorded by a Cauchois-type cylindrically bent Transmission Crystal Spectrometer (TCS). The absolutely calibrated spectrometer provides an unprecedented resolution of inner shell transitions (K x-ray radiati ...

8. A method for organic/inorganic differentiation using an x-ray forward/backscatter personnel scanner
Topic: Radiation Physics
Published: 9/10/2013
Authors: Jack Leigh Glover, Lawrence T Hudson
Abstract: A method is proposed for performing organic/inorganic materials discrimination using an x-ray forward/backscatter scanner. The method is demonstrated using a commercially available personnel security-screening system and requires only image post proc ...

9. Test Report-Exposure and Ambient dose Equivalent Rate Measurements in Support of the ITRAP+10 Testing
Series: Technical Note (NIST TN)
Report Number: 1800
Topic: Radiation Physics
Published: 8/1/2013
Authors: Leticia S Pibida, Ronaldo Minniti, Larry Lee Lucas, C Michelle O'Brien
Abstract: In this work we studied the response of two different Victoreen® instruments as a function of the exposure rate, the instrument orientation and photon energy. The rate dependence for both instruments is of the order of 8 % over the range of expos ...

10. Comparison of the standards for air kerma of the NIST and the BIPM for 60Co gamma radiation
Topic: Radiation Physics
Published: 7/31/2013
Authors: Ronaldo Minniti, C Kessler, P J Allisy-Roberts
Abstract: An indirect comparison of the standards for air kerma of the National Institute of Standards and Technology (NIST), USA, and of the Bureau International des Poids et Mesures (BIPM) was carried out in the 60Co radiation beam of the BIPM in September 2 ...
