Description
Mohammad Nadi and six co-authors test, in a 2025 study, a clay and iron-mineral mix as a liner for low-level waste landfills. A safe liner must block water flow and hold its strength. It should also shield radiation. The team blended goethite, an iron mineral, into bentonite clay at shares from ten to fifty percent.
Lab measures, computer simulation, and database checks all pointed the same way. The blends blocked gamma rays better as the goethite share rose. Gains reached about a fifth to a quarter at the tested energies. More goethite halved cohesion but doubled the friction angle. Strength peaked at a thirty percent blend, while water flow rose with goethite share. The mix looks promising where radiation shielding matters most.
