Calculation and Research of γ-ray Air Attenuation Coefficient at Different Altitudes
Journal of Isotopes, 2021 In the process of aviation gamma dose rate measurement, due to the large altitude span, the gamma-ray air attenuation coefficient will be affected by altitude, temperature, air pressure and air density, so corresponding corrections are needed.

Near K-edge linear attenuation coefficients for amorphous and crystalline GaAs [PDF]
Radiation Physics and Chemistry, 2003 Abstract We present tabulated near K-edge linear attenuation coefficients for stoichiometric crystalline and amorphous gallium arsenide. The coefficients were derived from total electron yield photocurrent measurements at the Daresbury Synchrotron Radiation Source and show considerable near-edge structure when compared to curves generated from ...

Experimental Comparison of Empirical Material Decomposition Methods for Spectral CT [PDF]
, 2015 Material composition can be estimated from spectral information acquired using photon counting x-ray detectors with pulse height analysis. Non-ideal effects in photon counting x-ray detectors such as charge-sharing, k-escape, and pulse-pileup distort the

On the attenuation coefficient of monomode periodic waveguides [PDF]
, 2011 It is widely accepted that, on ensemble average, the transmission T of guided modes decays exponentially with the waveguide length L due to small imperfections, leading to the important figure of merit defined as the attenuation-rate coefficient alpha = -

Determination of Linear Attenuation Coefficients of Materials by Using Timing Method
Instrumentation Science & Technology, 2009 Abstract In this work, gamma-ray linear attenuation coefficients of aluminum (Al) and lead (Pb) materials were determined by using timing method. The used setup is different from the conventional ones. The goal of the presented setup is the fact that it is used the timing technique.
