Effect of the photon intensity selected at various positions under the photopeak on the mass attenuation coefficient of x-rays

The variation in the value of the mass attenuation coefficient of x‐rays in aluminium was studied by counting photons under various positions in the photopeak employing a proportional counter spectrometer system with a good geometrical set‐up. The effect of (small angle) scattering was also examined...

description	The variation in the value of the mass attenuation coefficient of x‐rays in aluminium was studied by counting photons under various positions in the photopeak employing a proportional counter spectrometer system with a good geometrical set‐up. The effect of (small angle) scattering was also examined using three different sets of collimators of diameter 9, 6 and 3 mm and employing both a pure x‐ray source (55Fe) and a mixed radiation source (57Co). The μm values obtained at the FWHM position for each set of collimators agree closely with the theoretical values.
