The clover sample IAEA-156 was harvested within a small geographical region in Austria in the summer of 1986. It was anticipated that the material would be contaminated with radioactive fallout resulting from the Chernobyl incident in April 1986. This material was γ-sterilized to ensure long-term stability of the material by inhibiting microbial action.
