Improved techniques for measuring x-ray mass attenuation coefficients

Optical Engineering, 2006
We apply the x-ray extended-range technique (XERT) to measure mass attenuation coefficients over one order of magnitude more accurately than previously reported in the literature. We describe the application of the XERT to the investigation of systematic effects due to harmonic energy components in the x-ray beam, scattering and fluorescence from the ...

Mass attenuation coefficients of saccharides for low-energy X-rays

Radiation Physics and Chemistry, 2005
Abstract Mass attenuation coefficients have been measured for mono- and disaccharides at photon energies 5.947, 6.460 and 14.413 keV. The measured values are compared with theoretical calculations. The agreement between experiment and theory is generally within 5%.

Characterization of Mass Attenuation Coefficients as a Function of Experimental Geometry

Instrumentation Science & Technology, 2015
Mass attenuation coefficients of H2O, PbO, and cellulose were determined using 59.5 keV gamma energies with CdTe and NaI (Tl) detectors at five different source-sample distances. The pencil beam method was used to measure the mass attenuation coefficients. All experimental mass attenuation coefficients were compared with simulated results.

Effect of geometry on mass attenuation coefficient of β-particles

The International Journal of Applied Radiation and Isotopes, 1984
Abstract The mass attenuation coefficient of β-particles in aluminum is determined for five different β-emitters covering the end-point energy range from 0.4 to 2.3 MeV adopting two extreme geometries, namely the good geometry setup and the 2π geometry setup.
