ABSTRACT:
This invention provides for a method of sterilizing a chemical composition contained within a closed container (20). The chemical composition is initially mechanically filtered (12) and then the containers (20) are closed and hermetically sealed within a first sealing layer (24). The first sealing layer (24) and the chemical container (20) form a single layer sealed enclosure (26) which is then encased within a second sealing layer (30) and hermetically sealed to form a second layer sealed container enclosure (32). The second layer sealed container enclosure (32) is then inserted into a carton (36) having a third sealing layer (38) lining. The carton is closed and then irradiated with gamma radiation at a predetermined dosage level to sterilize the contents of the container (20). The closed cartons (36) are then transported to operational sites where the plurality of sealing layers (24, 30 and 38) provide for optimized contamination reduction.
