The lake sediment material IAEA-SL-1 was collected and prepared by Drs. J.C. Richie and C. Cooper (US Department of Agriculture, Agricultural Research Service, USDA Sedimentation Laboratory, Oxford, Mississippi, USA) and donated to the IAEA. The sediment was collected at the Sardis Reservoir, Panola County, Mississippi, USA (water depth: 15 m). The material was dried in an oven, then ground and sieved. The fraction of the material which passed through a 0.1mm sieve was sent to the IAEA for further processing. This material was γ-sterilized to ensure long-term stability of the material by inhibiting microbial action.
