Gamma Irradiation
What is Gamma Irradiation ?
Gamma Irradiation is a cold, non-chemical sterilization and preservation technology that uses controlled doses of gamma rays to eliminate harmful microorganisms, insects, and parasites from products. It does not make products radioactive.
This technology is widely used across food processing, healthcare, pharmaceuticals, agriculture, and industrial sectors to improve safety, extend shelf life, and meet national and international quality standards.
Gamma irradiation works without heat or moisture, making it ideal for sensitive products where traditional treatments may degrade quality.

How Does Gamma Irradiation Work ?
-
Product Receipt & Inspection
Products are received, documented, and inspected for packaging integrity and irradiation suitability.
-
Pre-Irradiation Quality Check
Product category, density, dose requirement, and regulatory compliance are verified.
-
Loading into Irradiation Carriers
Products are placed in specially designed carriers or totes to ensure uniform exposure.
-
Gamma Exposure
The carriers move automatically around a sealed gamma source (usually Cobalt-60). Gamma rays penetrate the product and disrupt the DNA of microorganisms, rendering them inactive.
-
Dose Monitoring & Validation
Dosimeters measure absorbed radiation to confirm the required dose has been delivered accurately.
-
Unloading & Post-Irradiation Testing
Products are unloaded and may undergo microbiological or quality testing.
-
Sterilization
Achieve sterilization or significant microbial reduction

Key Terminologies of Gamma Irradiation
Sources
Sources Used in Gamma Irradiation
"Gamma sources like Cobalt-60 and Cesium-137 are used."
Gamma irradiation commonly uses sources like Cobalt-60 and Cesium-137. These radioactive materials emit high-energy gamma rays for applications like sterilization and food preservation.
-
High penetration power
-
Stable and reliable radiation output
-
Long half-life (~5.27 years)
-
Used in select research applications
-
Less common due to handling complexities
we believe sustainability and trust. Cobalt-60 (Primary Source) is to bridge the gap between traditional farming and modern solutions—helping farmers grow.
-
Premium quality seeds, eco-friendly fertilizers
