- Radiation Protection is a crucial aspect in controlling the impacts of radiation to environmental health. Therefore, every nuclear installation and radiology unit has to mainly prioritize the implementation of radiation protection to protect their workers and society surrounding the installation. High density concrete, composed of barite stone, iron sand and the additive substance of viscocrete-10, and made by preplaced method, is investigated in this research as shield material. The source of radiation used are the following gamma-ray: 152Eu with the selected energy of 121,7824 keV, 131I with the energy of 364,5 keV and 137Cs with the energy of 661,6 keV. The quality examination of concrete with barite and iron sand comes up with the following results: a compression strength of 15,38 MPa and the specific gravity of 3,121 gr/cm3. The attenuation coefficient (3) yielded the equation of y = 0,6053e-0,0008x that applies only for the energy radiation 121,7824 keV up to 661,6 keV. If this attenuation coefficient is compared to normal density concrete with specific gravity of 2,35 gr/cm3, the attenuation coefficient of high density concrete is higher, so that the radiation of shield thickness will be more efficient. Keywords: Attenuation Coefficient, Preplace Method, Shield Radiation, Viscocrete-10.
