Sterilizing Units, Ionizing Radiation
Definition : Sterilizing units designed for total inactivation of microorganisms that are or may be present on medical devices using ionizing radiation (typically gamma, but x-ray and electron beams are also used) sources. These units usually include a treatment chamber with shelves on which packed devices to be sterilized are placed; a source of ionizing radiation (e.g., gamma radiation, typically obtained from a cobalt 60 source); and controls to regulate the time of the procedure. Ionizing radiation sterilizing units are available in a variety of shapes and sizes; these units are frequently supplied as complete installations and their use requires special safety protection for the operators. Radiation sterilizing units are mainly used by manufacturers to irradiate single-use medical devices (e.g., syringes, needles) and supplies, even after the devices are packed and ready to deliver; they may be used also in large healthcare facilities that sterilize a great volume of devices.
