Beyond radiocarbon dating, radioisotopes serve several other practical purposes. In electricity generation, controlled nuclear fission inside a reactor (fissile material plus a moderator to slow neutrons, cadmium control rods to regulate the chain reaction, and a coolant loop to carry heat to a steam turbine) offers a clean, carbon-free, extremely energy-dense alternative to burning fossil fuels -- fissioning just 1 gram of uranium-235 releases energy equivalent to burning about 3 tons of coal. In medicine, short-lived diagnostic isotopes (e.g. chromium-51 for spleen imaging) limit a patient's radiation exposure during imaging, while longer-acting therapeutic isotopes (e.g. phosphorus-32 for leukemia, cobalt-60 and iodine-131 for cancer treatment) are used to destroy abnormal cells.
