Abstract

A radiation barrier system comprising: a chemically reactive base layer; a first layer at least partially disposed above the base layer; the first layer comprising a first soil; a second layer at least partially disposed above the first layer; and the second layer comprising a second soil. The chemically active base layer is a hydro-geochemical filter barrier. The chemically active base layer mitigates soluble uranium or uranyl ion transport. The chemically active base layer filters out uranyl ions. The uranyl ions are filtered out by a process of surface adsorption to a phase added to a lithified soil composition.

IPC Classes  ?

• G21F 3/00 - Shielding characterised by its physical form, e.g. granules, or shape of the material
• G21F 1/00 - Shielding characterised by the composition of the material

Abstract

A composition and method for sorbing a mobilized metal which can optionally include uranium, and which can optionally be used for capping uranium-containing mining tailings. The method can include forming a layered structure atop the metal-containing mining tailings which sorbs the metal and prevents it from being discharged as surface water runoff and which prevents it from being released into groundwater.
