    Industries

    Materials with moisture often develop mold, yeast, bacteria and other microorganisms.

    As the FDA and other regulatory bodies continue to tighten inspection and compliance requirements, various imported and domestically manufactured products are increasingly being tested, detained, or recalled due to microbial contamination. Sterigenics’ radiation technologies can stop the progression of microbial growth and damage to products and help make the products safe for distribution.

    If you are a restoration company, government agency, or manufacturer of hygiene and personal care products,, Sterigenics is a critical partner for reducing molds, yeasts, and bacteria using FDA-approved technologies.

    What is Gamma?

    Gamma is a pure form of energy characterized by its deep penetration and low-dose rates. Gamma irradiators are powered by Cobalt-60, a radioisotope that kills microorganisms throughout a product, including bacteria, molds, and yeasts. The applied radiation dose is tailored to the type and level of contamination while maintaining product integrity and performance.

    What materials and products can be irradiated to eliminate or decrease microbial contamination?

    The FDA-approved, radiation-based Gamma solution treats a variety of materials and finished goods, including:

    • Cosmetic cleaning towelettes
    • Baby wipes
    • Eyelid and ocular hygiene wipes
    • Documents such as binders and leather covers
    • Toys
    • Clothing
    • Novelties, gift items, and accessories
    • Plastic components (tubes, bottles, etc.)

    Modality for microbial reduction

    Radiation-based Gamma processing to eliminate or decrease molds, yeast, and bacterial contamination is widely used in both the restoration and salvage industries. Products are typically placed in sturdy cardboard cartons, targeting consistent weights to help to ensure uniform dose delivery. This process leaves no residuals to the product. The packaging remains intact, and the Gamma radiation penetrates through the cartons to reduce microbial contamination—helping protect product safety, shelf life, and consumer health.
