Webmeasurements of gamma-ray attenuation through the sedi-ments and rocks, which relates to their wet-bulk density. This was done by a system called Gamma Ray Attenuation Porosity Evaluator, which will hereafter be referred to by its acronym GRAPE. The weight-volume method will be discussed first followed by a discussion of the GRAPE method. WebHeavy Metal Oxide (HMO) containing glass materials serve the purpose of radiation shielding owing to their optical transparency as well as radiation attenuation power. In this work, a glass system Li 2 O-K 2 O-B 2 O 3-HMO containing various HMOs like SrO/TeO 2 /PbO/Bi 2 O 3 was analyzed for the radiation shielding properties.
