X-ray Absorption Fine Structure Studies of Speciation of Technetium in Borosilicate Glasses
A series of glass samples were prepared analogously to high level waste glass using either glass frit or glass precursors combined with a high level waste surrogate containing NaTcO4. Three different technetium s...
