摘要

In view of low cost, hydrogenous materials such as Polyethylene and CH2 have been developed and beingused currently by NASA as an effective galactic cosmic radiation shields in place of aluminum for hull design ofspacecraft . Lead, steel and concrete which are currently being used as effective radiation shields for the treatment ofrooms equipped with Electron accelerators are found be quite expensive. Hence, it is necessary to use alternative lowcost material which serves as an effective radiation shield. In the present study, an attempt has been made to measuregamma-ray mass attenuation coefficient, effective atomic number and absorbed dose rate of the compounds such asNH4C1, KC1, and CdO using various gamma sources of energies 356, 511, 662, 1173, and 1332 keV. These parametersare expected to gives vital information on the selection of shielding materials.
