Integrated X‐Ray, Gamma Radiation, and Micro‐CT Techniques for Quantitative Wood Characterization

X-Ray Spectrometry, EarlyView.
ABSTRACT The present research integrates microcomputed tomography (micro‐CT), x‐ray fluorescence, and gamma‐ray transmission to quantitatively characterize wood species. A total of 22 samples from seven species were analyzed for density (ρ), linear attenuation coefficient (μ), Compton scattering, micro‐CT gray values (GV), porosity, mass attenuation ...
