Abstract
Package components for the radiochemical sterilization of medical devices contain paraformaldehyde as the precursor of the radiolytically generated, sterilizing dose of formaldehyde, premixed with a particulate solid dispersant of, preferably, polyethylene or silica gel, which facilitates the free passage of the formaldehyde to the package gaseous environment or additionally, absorbs trace amounts of moisture in the package, thus, facilitating the device manufacturing process and increasing shelf-stability.
