HEREDIA CARMONA, Julio e DIAZ RIZO, Oscar. Experimental and Monte Carlo determination of mass absorption coefficients for /
beta particles in organic compounds. Nucleus [online]. 2009, n.45, pp. 26-31. ISSN 0864-084X.
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.
