Milk Powder

The milk and whey powders (IAEA-152 and IAEA-154) were donated to the IAEA by a milk processing facility in the former USSR whereas IAEA-321 (milk powder) was collected from an European dairy products processing plant. The materials were produced from cow’s milk obtained from animals that had grazed on land contaminated with radioactive fallout resulting from the Chernobyl incident in 1986. These materials were γ-sterilized to ensure long-term stability of the material by inhibiting microbial action
