Radiation protection is one of the external radiation protection efforts.Concrete is the material for making external radiation shields other than lead, steel, and other heavy materials.According to [2], concrete material for a good radiation shield is made from sand from the south coast of Yogyakarta with an average linear attenuation coefficient value of 0.801697695 cm^(-1) and an HVL value with an average of 0.865070204 cm.Therefore, this study aimed to determine the consistency of sand from Parangtritis beach to Congo beach influencing the linear attenuation coefficient of radiation shielding concrete.The research used is to use a sample of beach sand moulded into concrete with a size of 20 cm^2 with a thickness of 5 cm and then mixed.Data analysis was carried out using the equation Dx = Do.e-µx to get the linear attenuation coefficient value.The data obtained are compared to determine the consistency of beach sand in affecting the linear attenuation coefficient of radiation shielding concrete.The study's results showed that the highest liner attenuation coefficient was produced by concrete with the primary material of Trisik beach sand with a value of 1.314044724 cm^(-1).On the other hand, the lowest linear attenuation coefficient value is produced by concrete based on Parangtritis beach sand with a value of 0.939604673 cm^(-1), so that beach sand from Parangtritis beach to Congo beach does not have consistency in influencing the attenuation coefficient of the antiradiation concrete liner.
