    Area of Science:

    • Radiation sterilization
    • Statistical process control
    • Metrology

    Background:

    • New regulatory requirements mandate accounting for measurement uncertainty in product release.
    • Traditional sterilization process controls may not adequately address variability.
    • Ensuring product safety and efficacy requires robust control strategies.

    Purpose of the Study:

    • To establish a novel statistical process control (SPC) method for sterilization.
    • To integrate measurement uncertainty into sterilization dose determination.
    • To minimize product rejections while maintaining sterilization assurance.

    Main Methods:

    • Development of a probability-based SPC framework.
    • Application of the method to gamma and electron-beam sterilization processes.
