产品详细介绍
The IAEA-SL-3 lake sediment was collected from the Neusiedlersee, located some 80 km south-east of Vienna, Austria. The material was collected directly from the top layer of the sediment using a mud pump and then coarse particle were removed in the field. After drying, the material was milled to give a particle size less than 71 μm. This material was γ-sterilized to ensure long-term stability of the material by inhibiting microbial action.
