Abstract

In order to investigate the bparticles absorption in organic compounds, an experimental arrangement was designed. A Monte Carlo transport code was also used to simulate this process. This allowed reporting for the first time m () values in several organic compounds for / isotopic sources. The obtained experimental and calculated values showed a good concordance. Methodological aspects of the µ () determination concerning the range of the absorber’s superficial density are discussed.
