Mass-attenuation coefficients of beta particles

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. Thus, the range distributions of the β particles are found. The mass-attenuation coefficient is obtained as the slope of the semi-log plot of integral range distribution. This method is applied to obtain the mass-attenuation coefficients of 204 Tl and RaE β particles in Al, Cu, Ag and Pb.
