Description
|
A batch of approximately 50 kg of cotton cellulose powder was homogenized at the Agency's Laboratories Seibersdorf. The material was homogenized in a rotating plastic drum for 70 hours and then bottled into plastic containers each containing approximately 25 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. |
