Abstract:
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.
