The effects of irradiation technologies on some polymers commonly used in SUDs - (PPT)

摘要

Most medical devices must be sterilised prior to be used. Sterilisation methods available are: 1. Ionising Radiation, 2. Gas Technologies (EO, mixed gaz - EO/CO~2, Plasma), 3. Steam. When opting for ionising radiation as sterilisation method of choice, the following fact must be known and understood: "Ionising radiation can cause significant damage and degradation to polymers due to the energetic secondary electrons released from the primary irradiation event." Type of ionising radiation available and commonly used for the sterilisation of medical devices (SUDs): 1. Gamma Radiation (Cobalt 60), 2. Beta Radiation (Electron Beam), 3. X-ray Radiation (Electron Beam converted to X-Ray).
