Our Gamma Sterilization Process

At GAMPPL, we recommend that all products arrive in their final packaging, as efficient packing is critical to achieving consistent and effective sterilization/Irradiation results.

The gamma sterilization/Irradiation process begins with loading products into irradiation containers (tote boxes). These containers are transported into the irradiation chamber via a specially designed carrier system, which operates at a controlled speed determined by the cobalt-60 source strength and the required dose.

Inside the chamber, each tote box is strategically positioned on either side of the source to ensure uniform radiation exposure. As the products pass through the irradiation zone, they receive the validated dose, ensuring they are 100% sterilized/Irradiated or disinfested and ready for immediate use or distribution.

The entire process is monitored and validated by our state-of-the-art dosimetry laboratory, ensuring precise dose delivery and full compliance with regulatory standards.

At GAMPPL, each tote box can accommodate a maximum weight of 45 kg, and the external dimensions of the boxes should not exceed 590 mm (L) × 430 mm (W) ×1100 (H) mm.

For optimal processing We recommend using individual final packaging boxes or containers weighing approximately 15 kg, with dimensions of 590 mm (L) × 430 mm (W) × 350 mm (H). The product should be evenly distributed within each box to ensure consistent dose delivery during sterilization/Irradiation. With these specified Conditions, up to three such boxes can be loaded into a single irradiation container (tote box) for effective and efficient processing.

In cases where it is not possible to follow the recommended box size and weight, the packaging must still comply with the maximum allowable dimensions and weight of the tote box (i.e., 560 mm × 430 mm × 1100 mm, up to 45 kg). Any deviations from the recommended configuration will be charged accordingly based on the number of  boxes for processing.
