What Are The Properties Of Cobalt-60?

Properties of Cobalt-60 Cobalt 60 half-life is 5.2713 years which is one of its main advantages being a high-intensity gamma-ray emitter. It has the longest half-life among all the Cobalt isotopes. Isotopes: Isotopes are elements with the same number of protons but they differ in the number of neutrons. What Read more…

Why Should Cobalt-60 Be Used?

What is it used for? Co-60 is used medically for radiation therapy as implants and as an external source of radiation exposure. It is used industrially in leveling gauges and to x-ray welding seams and other structural elements to detect flaws. Is cobalt-60 harmful to the environment? Although cobalt is Read more…

How Does Cobalt-60 Sterilize?

Cobalt-60 is type of ionizing radiation. Gamma rays from a source penetrate the targeted material and knock electrons from orbit. For sterilization applications this has the effect of disrupting DNA, which renders any microorganisms present nonviable. How does radiation sterilization work? Radiation kills germs that can cause disease and neutralizes Read more…

How Does Cobalt-60 Sterilize Food?

Food irradiation is the process of exposing boxes or pallets of food products to radiation from a Cobalt-60 source. The ionizing radiation destroys dangerous contaminates in foods such as bacteria, viruses, fungi and insects. The process is not new; it’s been around for the past 60 years. How does cobalt-60 Read more…

The name cobalt green has also been used for some commercial paints that have a mixture of Cobalt blue and Chrome yellow. Is cobalt green toxic? Composition and Properties Read more…

Why Is Cobalt-60 Used In Gamma Knife?

Gamma Knife and Cancer Treatment Stereotactic Radiosurgery using Cobalt-60 therapy allows doctors to deliver higher doses of radiation to tumours, while limiting damage to the surrounding healthy tissue and organs. Why is cobalt-60 a good source of gamma rays? Cobalt-60 (60Co) and caesium-137 (137Cs) are the most widely used sources Read more…

How Common Is Cobalt-60?

Cobalt-60 is produced as a result of weapons testing or in other nuclear reactions. Since cobalt-60 has a short half-life, there is no significant presence of the isotope in the general environment at this time. Is cobalt-60 rare? Though relatively rare, exposure has also occurred by accidental mishandling of a Read more…
