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.

Mass attenuation coefficients of β+-particles

Applied Radiation and Isotopes, 1999
Abstract The beta-spectra for the allowed transition and the first forbidden unique transition are calculated with enough accuracy. By applying them to the semiempirical transmission equation of monoenergetic electrons and positrons, we obtained the mass attenuation coefficients of beta-particles.

Soil mass attenuation coefficient: Analysis and evaluation

Annals of Nuclear Energy, 2014
Abstract The mass attenuation coefficient ( μ ) is an important parameter to characterize the penetration and interaction of gamma-rays in the soil. Accurate determinations of μ are important to obtain representative values of soil physical properties by gamma-ray attenuation technique. In this study, the effect of collimator size (2–4 mm diameters)
