Radiation sterilised personal protective equipment
Discolouration and odour formation

Abstract
The use of radiation to sterilise medical devices, food, beverages, and personal protective equipment is well established. Although gamma radiation remains the most common method, alternatives such as X-ray sterilisation are gaining popularity. A potential concern with sterilising polymers through irradiation is the alteration of the product. Besides functional changes, which must be avoided for obvious reasons, discolouration and malodour development can also occur. Based on the literature, primarily observational studies, these phenomena were examined in terms of their causes, effects, and potential control measures. Since the fundamental chemistry of gamma and X-ray radiation is essentially the same, their secondary effects on polymers are also similar. However, process parameters like dose rate and dose uniformity ratio may favour X-ray over gamma radiation.
