One of the most important gamma radiation quantities with respect to radiation dosimetry and health physics applications is mass–energy absorption. Direct measurements of the coefficient of mass–energy absorption, μen/ρ, are difficult and typically recourse is taken to theoretical computations. In ...

Tables and graphs of the photon mass attenuation coefficient mu/rho and the massenergy-absorption coefficient my(en)/rho are presented for all of the elements Z=1 to 92, and for 48 compounds and mixtures of radiological interest. The tables cover energies of the photon (x ray, gamma ray,...
biological and industrial dosimetry of ionizing radiations. Hine [13] pointed out that, in photon interaction in the composite materials, the atomic number cannot be represented uniquely by a single number across the entire energy region, as in the case of pure elements. This number for composite...
Snowplow calculations with various density and current profiles are used to determine the dependence of these quantities on the profile shapes. The authors' results demonstrate the importance of using accurate experimental density and current profiles with radiation-scaling analyses....
energy dispersive analysisL-seriesEnergy dispersive X-ray spectroscopy has insufficient resolution to separate the individual lines of low energy L-series peaks. However, the mass absorption coefficients for L伪 and L尾 radiation differ significantly for elements with atomic numbers between 21 and 32....
