Our gamma irradiation indicators use the latest technology
CleanMark’s gamma irradiation indicators use chemical compounds that undergo irreversible color changes when exposed to gamma radiation, giving you visible proof that the correct dose has been delivered.
Dose-specific response
Our labels are calibrated to change color only at specific radiation levels, ensuring a reliable signal when the minimum validated dose for sterilization has been reached.
Permanent color shift
Once our gamma irradiation indicator reacts, the color change is irreversible, making them perfect for long-term verification for quality assurance and compliance.
Custom configuration
Need to combine a gamma irradiation indicator with barcodes, batch numbers, or surface-specific adhesives? We’ll design a label that meets your exact process and packaging needs.
