Linear attenuation coefficients of regular as well as irregular shaped archaeological samples of FaLG (flyash-lime-gypsum) of unknown thickness have been measured employing 'simplified two media' method. Seven different liquid materials plus air have been used as media to measure attenuation coefficient of these samples. Obtained results have been compared with those for regular shaped samples. Experimental values have also been compared with theoretical values calculated from FFAST and XCOM. A good agreement has been observed between experimental and theoretical values. Present measurements employing 'simplified two media' method have been reported for the first time for checking its validation and reliability. (C) 2011 Elsevier Ltd. All rights reserved.
