Abstract: The linear attenuation coefficients, the practical ranges and the stopping powers of beta particles in three elements and eight polymers have been determined. Beta particles of kinetic energy 2.288 MeV obtained from the radio-isotope 90Y are uded in transmission technique with and without collimator, the comparison between the two arrangements is discussed in terms of build up factor. Empirical formula of the linear attenuation coefficients of broad beam and their dependencies on the material density and the source detector distance are also discussed. A good agreement of our values with those published previously are obtained for aluminum, copper and iron.
