Top 10 Companies in the Global Cobalt‑60 (Co‑60) Sealed Sources Market (2026): Market Leaders Powering Global Innovation

MARKET INSIGHTS

Global Cobalt‑60 (Co‑60) Sealed Sources market size was valued at USD 602.1 million in 2025. The market is projected to reach USD 912.8 million by 2034, reflecting an upward trajectory that underscores the growing importance of high‑dose radiation sources across healthcare and industrial sectors.

Cobalt‑60 (Co‑60) sealed sources are radioactive devices containing the cobalt‑60 isotope that are hermetically encapsulated in a durable container—typically stainless steel or a double‑walled capsule. Engineered for high‑dose‑rate applications, these sources play a pivotal role in industrial radiography for non‑destructive testing (NDT), medical sterilisation of single‑use devices, and radiation therapy. The robust sealed design ensures complete containment of the radioactive material, providing essential shielding that minimises radiation exposure risks for personnel and the environment.

The market growth is primarily driven by the expanding healthcare sector’s demand for sterilisation and cancer treatment, alongside increasing infrastructure development that requires non‑destructive testing. For instance, in May 2024 Nordion announced the delivery of a new Co‑60 shipment to Steris AST in Florida to support the growing demand for medical device sterilisation. However, the market faces challenges from stringent regulatory frameworks and the high cost of source replacement. Key companies operating in this market include Nordion, QSA Global, Eckert & Ziegler, and China Isotope & Radiation Corporation (CIRC), who provide a wide portfolio of sealed sources for various applications.
