Cobalt-60 - Wikipedia
Cobalt-60 (60 Co), is a synthetic radioactive isotope of cobalt with a half-life of 5.2713 years. It is produced artificially in nuclear reactors. Deliberate industrial production depends on neutron activation of bulk samples of the monoisotopic and mononuclidic cobalt isotope 59 Co. ... Fetch Here

Cobalt-60 - An Overview | ScienceDirect Topics
Cobalt 60 (60 Co) is often the ideal mode of radiation for treating laryngeal cancer. For primary treatment of laryngeal cancer, 60 Co allows adequate dosing of the superficial tissues. Historically, great concern has been expressed that 6-MV photons have too large a buildup region and can potentially underdose superficial tissues. ... Retrieve Content

Gamma rays are another form of photons used in radiotherapy. Gamma rays are produced spontaneously as certain elements (such as radium, uranium, and cobalt 60), which release radiation as they decompose, or decay. Each element decays at a specific rate and gives off energy in the form of gamma rays and other particles. ... View Document
