Abstract
The mass attenuation coefficients of the LRd-A(3) Brazilian soil has b een measured at seven energies in the range of 59.5-1408.0 keV. Radioa ctive isotopes were used as sources of monoenergetic gamma radiation i n a narrow-beam collimated geometry. Experimental errors were in the r ange from 0.4 to 3.1%. Also mass attenuation coefficients of six Brazi lian soils have been calculated in the energy range from 10 keV to 10 GeV to study the influence of chemical composition. Comparison between data, theoretical calculated values and data from the literature has been done for the LRd-A(3) soil.
