Two sediment samples were collected in Queensland region, Australia using a Van Veen type sampler. One site was sampled in Townsville Marina and the other in Townsville Ross River. Frozen samples were sent from Brisbane to IAEA laboratories in Monaco. Sediment sample was freeze-dried, micronized at 20 um and ?-irradiated at doses ranging from 27 to 39.5 kGy. The final powdered composite sediment, about 15 kg, was homogenized by mixing it in a stainless-steel rotating drum for three weeks.
