Goldcrest Radiation Chemical Process Indicators: Trusted Solutions For Gamma And E-Beam Irradiation

Customark is proud to spotlight the Goldcrest Radiation Chemical Process Indicators (CPIs)—a reliable and environmentally conscious solution for monitoring Gamma and E-beam irradiation processes. These indicators are produced by Goldcrest Labels, a brand now part of the Customark family following its recent acquisition. This strategic partnership allows us to offer an even wider range of high-quality labelling solutions, tailored to meet diverse industry needs.

Goldcrest CPIs: Precision in Process Monitoring

Goldcrest Radiation CPIs are designed to help users monitor whether irradiation conditions have been successfully met. Manufactured without lead or toxic heavy metals, and using a latex-free pressure-sensitive adhesive, these indicators are not only safe for use but also environmentally friendly.

Key Features

Physical Properties

  • Process: Suitable for Gamma or E-beam irradiation.
  • Dimensions: Standard 12.5 mm size or bespoke options available.
  • Packaging: Supplied in rolls of 5,000 indicators for convenience.
  • Chemical Indicator:
    • Initial Colour: Yellow.
    • Signal Colour: Red (varies based on dose and conditions).

Performance Characteristics

Goldcrest CPIs utilize a radiation-specific chemical reaction to indicate whether the irradiation process has met the necessary conditions. Upon exposure to doses starting at 10 kGy, the indicator transitions from yellow to a shade of dark orange or red. This colour change is irreversible under most conditions and serves as a reliable indicator of successful irradiation.

Note: Variations in signal colour may occur based on factors such as load configuration, cycle time, and dose. Any clear transition from yellow to orange/red is considered acceptable under ISO 11140-1 Type 1 standards.

Instructions for Use

  1. Apply an indicator to each item, pack, peel pouch, or tray intended for irradiation.
  2. Process the items as required.
  3. Post-irradiation, inspect the indicator:
    • A change to orange/red signifies successful exposure.
    • If the signal colour is not achieved, reprocess the load with a new indicator.

Important: Store exposed indicators away from pH-basic environments (e.g., cleaning products) to prevent unintended colour reversion.

Compliance and Disposal

Goldcrest CPIs comply with ISO 11140-1:2014 standards, ensuring reliability and performance. They are also environmentally safe and can be discarded as general waste after use.

Why Goldcrest CPIs?

These indicators are ideal for industries requiring irradiation processes, such as healthcare, pharmaceuticals, and manufacturing. Their robust design and compliance with international standards make them a trusted choice for ensuring process accuracy.
