Contamination control depends on the integrity of personal protective equipment (PPE). Radiation sterilisationis widely used to ensure PPE is free from microorganisms. But beyond sterility, changes in material properties such as discolouration and odour formation can influence operator perception, comfort, and compliance in cleanroom environments.
Polymers used in cleanroom PPE, like neoprene, polypropylene, polyethylene, nitrile, and latex, are susceptible to free radical reactions during radiation sterilisation. These reactions can lead to:
While these effects don’t necessarily compromise protective function, they can affect operator confidence and the perception of product quality.
Studies show that both gamma and X‑ray sterilisation have comparable microbicidal effectiveness, but they can trigger aesthetic changes in polymers. Research highlights explained in this newest white paper:
Understanding these nuances is vital for contamination control experts. PPE selection should consider not only sterility assurance and regulatory compliance but also material behaviour under sterilisation to maintain operator comfort and workflow efficiency.
Contamination control in pharma and life sciences is about more than sterility—it’s about trust, usability, and sustainability. We invite you to explore the full article for deeper insights into how radiation sterilisation affects PPE and how to optimise your selection process.
