The measurement of total mass attenuation coefficients of CoCuNi alloys

Journal of Quantitative Spectroscopy and Radiative Transfer, 2004
Abstract The total mass attenuation coefficients for Co, Cu, Ni elements and CoCu, CoCuNi alloys were measured at different energies with 11.88, 13.93, 17.59, 21.09 and 26.00 keV emitted an 241 Am point source using transmission arrangement. The gamma rays were counted by a Si(Li) detector with a resolution of 160 eV at

Mass-attenuation coefficients of beta particles

International Journal of Radiation Applications and Instrumentation. Part A. Applied Radiation and Isotopes, 1990
Abstract A method to obtain mass-attenuation coefficients of β particles is described. This method is based upon the simulation of β emission by means of the β energy spectrum. The range of the β particle is chosen as random incidence by means of range distribution of monoenergetic electrons which have the same energy as the β particle.
