It is known that in soils and sediments moisture adsorbed on particle surfaces and in the pore system significantly affects the behaviour of recoiling radon ((222)Rn) atoms after decay of parent (226)Ra, leading to increased (222)Rn emanation. As a first step in an effort to characterize the (222)Rn source term in mineralised sediments in the present study, complementing previous studies in the area, granitic esker sand samples were collected in order to test how moisture content affects (222… CONTINUE READING
