Content: Plutonium generators are not practical on  a large scale basis. But they are very desirable for special conditions. For example, they have been used to provide electrical power on space  probes and space vehicles. They have also been used in artificial pacemakers for  people with heart conditions. The isotope most commonly used for this  application is plutonium-238 because the radiation it gives off does not  pose a threat to people's health. Plutonium is also used as a fuel in nuclear power plants and in making  nuclear weapons ("atomic bombs"). The isotope used for this  purpose is plutonium-239. It is used because it will undergo nuclear  fission. Very few isotopes will undergo nuclear fission. Two isotopes of  uranium, uranium-233 and uranium-235, are among these.
