Hay Powder

The IAEA-V-10 material, lucerne hay, was grown on calcareous soil at Churn, Berkshire, UK, by the University of Reading and supplied to the IAEA Laboratories, Seibersdorf, by Dr. H. M. J. Bowen for further processing. This material was γ-sterilized to ensure long-term stability of the material by inhibiting microbial action.
