摘要：
The well-known code Stopping and Range of Ions in Matter (SRIM) and the more recent code AlfaMC were used in this work to evaluate the backscattering corrections required in the measurement of alpha particle sources. The differences found in the energy and angular distribution of backscattered particles for point sources mounted on backings of aluminum, silver, and platinum, were analyzed taking into account the models of multiple scattering included in each code. The lateral dispersion of alpha particles and the backscattering coefficients obtained with SRIM were in all the cases some greater than those derived with AlfaMC.
