Question
Cobalt-60 is a radioactive isotope that is commonly used for cancer radiation therapy. The cobalt-60 atom decays to the stable nickel-60 atom, releasing a beta particle (electron) and energy in the form of gamma rays: 60 Co rightarrow 60Ni + beta + gamma The relevant masses are as follows: Gamma rays are massless. If you captured the energy from the decay of a 1.13g pellet of isotopically pure cobalt-60, how long could you run a 40.0W light bulb? Express your answer to three significant figures and include the appropriate units. hours of light =Explanation / Answer
