The transmission of gamma-rays at the energies, 81, 356, 511, 662, 835, 127
4 and 1332 keV has been studied on the alloys brass, bronze, steel, aluminu
m-silicon and lead-antimony. The mass absorption coefficients have been mea
sured. The total interaction cross-sections and effective atomic numbers ha
ve been determined on the basis of mixture rule and compared with the resul
ts obtained from theory. (C) 2000 Elsevier Science Ltd. All rights reserved
