Ionising radiation processing is a method of using high-energy radiation to modify the properties of materials or to sterilize products. The radiation sources typically used are electron beams, X-rays, or gamma rays. These sources emit photons or electrons that carry enough energy to ionize atoms and molecules within the material being processed.

The primary applications of ionising radiation processing include sterilization of medical devices, food preservation, and modification of polymers. In medical sterilization, the radiation penetrates packaging and kills microorganisms without significantly increasing the temperature of the product, making it suitable for heat-sensitive materials. For food preservation, it can extend shelf life by reducing spoilage microorganisms and insects, and in some cases, it can eliminate pathogens. Polymer modification can include crosslinking, which improves strength and heat resistance, or degradation, which can be used to reduce molecular weight for specific applications.

The process is carefully controlled to ensure the desired effect is achieved without causing unwanted damage to the product. Dosimetry, the measurement of the absorbed radiation dose, is critical for process validation and control. Ionising radiation processing is considered a safe and effective technology when applied correctly, and it is widely used across various industries globally.
