Abstract: The damaging effect of radiation on materials including the biological systems has been subject of intense investigation to find out the nature and extent of the damage that takes place. Most of the living tissues are susceptible to massive damage even under low dose of radiation. However, little is known of flow characteristics of gamma rays as only few studies have been carried out. This study is mainly concerned on the absorption of gamma rays by artificial tissues. An artificial tissue was used in this study produces by jelly powder with mass 8 g and different volume of water in ratio 1: 15; 1 :30; 1 :45; 1 :60; 1:75; and 1 :90. In this study, source of gamma rays produces by Co-60. For preparation of artificial tissues, different volumes of water are used. Artificial tissues absorption coefficient is determined by using absorption coefficient equation. Geiger-Muller counter is presented in analyzing the impuls counting rate of gamma rays. The result for the artificial tissues absorption coefficient is represent in linear graph with absorption coefficient of each samples are 0.3385, 0.3402, 0.3415, 0.3424, 0.3448, 0.3461. Absorption coefficient for each artificial tissue can be determined from that graph by using the equation of absorption coefficient. From research result, absorption coefficient for each material is difference with others and also depends on quantum particles through the materials.
