Gamma Irradiators

Gamma irradiators consist of a shielded chamber containing a radioactive source. Products to be irradiated are placed within the chamber and exposed to gamma radiation for a controlled period. The radiation kills microorganisms, insects, and other pests, extending the shelf life of food and sterilising medical devices. Gamma irradiation can also be used to modify the properties of polymers and other materials. Supply chain considerations involve the availability of radioactive sources, shielding materials, and automated handling systems. Logistical challenges include the transportation of radioactive sources and the safe operation of the irradiator. Accessibility for developing countries is limited by the high cost and regulatory requirements associated with handling radioactive materials.

Gamma irradiators are a mature technology, widely used in industrial and medical settings.

Gamma irradiators use high-activity radioactive sources, requiring robust shielding and safety protocols to prevent radiation exposure. Source integrity and security are also critical safety considerations.

The radioactive sources used in gamma irradiators can be a security concern. Proper control and monitoring are necessary to prevent unauthorised access or misuse.

IAEA safeguards are essential for gamma irradiators, involving inspections, source accounting, and containment and surveillance measures to verify the peaceful use of radioactive sources.
