How does cobalt 60 decay
WebJan 30, 2024 · Since the decay rate is dependent upon the number of radioactive atoms, in terms of chemical kinetics, one can say that radioactive decay is a first order reaction process. ... The Cobalt-60 … WebThe cobalt-60 system is designed to deliver radiation in the shape of a sphere. To cover irregularly shaped tumors, several of these radiation spheres have to be used. If a metastasis is pear-shaped, for example, then two different sized spheres must be used to mimic the shape of the tumor. Newer systems automatically change the width of ...
