Description
|
A batch of approximately 200 kg of rye flour (prepared in an industrial mill) was homogenized at the Agency's Laboratories Seibersdorf. The batch was divided into four 50 kg lots. Each lot was sub-divided into four equal parts and a portion from each was re-combined to yield four new 50 kg batches. These batches were homogenized in turn by mixing them in a rotating plastic drum for 24 hours. The cycle of sub-dividing, combining and mixing was repeated once more. The material was then bottled into plastic containers each containing approximately 50 g. Finally, the samples were irradiated to a dose of 2.5 x 104 Gy using a 60 Co source to ensure long-term stability of the material by inhibiting microbial action. |
