How is cobalt-60 used to inspect industrial materials and treat cancer?

Cobalt-60 is a radioactive isotope produced by irradiating stable cobalt-59 with neutrons in a nuclear reactor. It is highly valued in both industrial and medical fields due to its gamma radiation emissions.12

Industrial Inspection

In industrial settings, cobalt-60 serves as a powerful tool for nondestructive testing, often replacing X-rays or radium. It is used to inspect materials to reveal their internal structure, identify hidden flaws, or detect foreign objects. Its utility is enhanced by the ability to machine or shape the metal into specific forms before irradiation to meet unique requirements.21

Medical Applications

In medicine, cobalt-60 is utilized for cancer therapy. It provides a more cost-effective alternative to radium, offering more homogeneous gamma radiation that can be precisely directed. Additionally, the isotope is used to sterilize medical equipment, ensuring safety in clinical environments.12
