    Absorption of gamma radiation by white cement samples as an artificial tissue
    (Universiti Malaysia Terengganu, 2008) Nur Kamal Hidayah Kamarulzaman
    There are many bad effects when we are expose by gamma ray. Due to that cause, this project has been run in order to investigate which materials are most efficient for gamma absorption. In this research, the material being used is white cement as the sample being test and the experiments have been carried out in three conditions which are wets, half dry and dry cement. From the research, wet cements show the most efficiency in rate of absorption and it almost equal to the rate of absorption of flexi glass. This results prove that molecule of water are influence the rate of absorption. So that, sample which the highest rate of absorption is wet sample with the rate of absorption is 0.27. In future, in order to produce better obstruction of gamma ray, white cement can be added with aluminium because the absorption rate of aluminium and white cement is good.
