One object is to provide an electron beam sterilization apparatus for sterilizing a preform product (P) by applying an electron beam while conveying the preform product (P), the apparatus comprising: an input star wheel (21) configured to convey the preform product (P) in a circular path; and an outer-surface electron beam application device and an inner-surface electron beam application device configured to apply an electron beam to the preform product (P) being conveyed by the input star wheel (21). A blocking short tube (31) is provided on a lower surface of the star wheel plate (22) of the input star wheel (21) so as to block radioactive rays produced by application of the electron beam and surround a central axis (1v) of the input star wheel (21). The blocking short tube (31) includes a ventilation space (34) formed therein.

An approach for curing ultraviolet sensitive polymer materials (e.g., polymer inks, coatings, and adhesives) using ultraviolet radiation is disclosed. The ultraviolet sensitive polymer materials curing can utilize ultraviolet light at different wavelength emissions arranged in a random, mixed or sequential arrangement. In one embodiment, an ultraviolet light C (UV-C) radiation emitter having a set of UV-C sources that emit UV-C radiation at a predetermined UV-C duration and intensity operate in conjunction with an ultraviolet light B (UV-B) radiation emitter having a set of UV-B sources configured to emit UV-B radiation at a predetermined UV-B duration and intensity and/or an ultraviolet light A (UV-A) radiation emitter having a set of UV-A sources configured to emit UV-A radiation at a predetermined UV-A duration and intensity, to cure the ultraviolet sensitive polymer materials.

A device (1) for irradiating titanium-dioxide-coated fibers with UV radiation includes a housing (2) that is filled with water. Bodies (4), including strips (5), which consist of quartz glass, are arranged in the housing (2). LEDs (7), which emit UV radiation, are paired with at least one of the longitudinal edges of the strips (5). UV radiation is uniformly emitted to the fibers by the strips (5), so that these fibers acquire anti-fouling properties.
