Hydrofracture grouts were characterized by optical microscopy, scanning electron microscopy, x-ray diffraction, and ..beta..-..gamma.. autoradiography. We examined laboratory-produced samples containing simulated wastes as well as actual radioactive samples of hydrofracture grout sheets obtained by core drilling. X-ray diffraction results revealed that both laboratory-produced samples and a core-drilled sample consisted primarily of calcium carbonate phases. Both sample types contained very small amounts of waste strontium or cesium, neither of which could be detected microscopically. Autoradiography revealed that /sup 90/Sr, /sup 137/Cs, and /sup 60/Co were still present in the core-drilled 20-year-old grout and that they had not migrated into the trapped shale fragments.
