Gamma Radiation Resistance

Most polymers can be degraded by photolysis to give lower molecular weight molecules. Electromagnetic waves with the energy of visible light or higher energy levels, such as ultraviolet light, X-rays and gamma rays are usually involved in such reactions. As gamma radiations are used in some sterilization processes, gamma radiation resistance characterizes the ability of polymers to withstand these sterilization methods.

To our knowledge, no specific standardized test method assesses the gamma radiation resistance of plastics. Ratings in the table below are based on an overall qualitative assessment.
