Energy resolution for accurate measurements of the X-ray linear attenuation coefficient

Radiation Physics and Chemistry, 2006
Abstract At energies below 100 keV, measurements of the X-ray linear attenuation coefficient μ , require either a mono-energetic source or a detector with good energy resolution. The majority of X-ray sources contain a spread of energies whilst detectors have finite energy resolution.

Effect of voltages on gamma-Ray linear attenuation coefficients for some semiconductors

2021
In this work, the change according to the different voltages (0, 5, 10, 15, 20 and, 25 V) of gamma-ray linear attenuation coefficients for GaSe, GaSe:Cd, GaSe:Sn, GaTe, GaTe:Cd, Ga0.9In0.1Se, GaTe0.4Se0.6, and GaTe0.8Se0.2 semiconductors have been measured by using an extremely narrow collimated-beam transmission method in the energy 59.54 keV.

On the measurement of the effective linear attenuation coefficient mueff in 60Co wedge fields.

Strahlentherapie und Onkologie : Organ der Deutschen Rontgengesellschaft ... [et al], 1996
It is difficult to obtain a correct measurement of mueff. Moreover, wedge calculations using a single mueff value are not correct. We present a program for the analysis of wedge measurements.The program employs parameters of an open field to correct the dosimetry of a wedge field. For this the ASCII export files of an MP3 (PTW) system are automatically
