Plutonium-238, 2015
By producing 50 grams of plutonium-238, Oak Ridge National Laboratory researchers have demonstrated the nation's ability to provide a valuable energy source for deep space missions. Plutonium-238 is a radioactive isotope of plutonium that has a half-life of years. Plutonium-238 is a very powerful alpha emitter and - unlike other isotopes of plutonium - it does not emit significant amounts of other, more penetrating and thus more problematic radiation. This makes the plutonium-238 isotope suitable for usage in radioisotope thermoelectric generators (RTGs) and radioisotope heater units 0 one gram of plutonium-238 generates approximately watts of thermal power. Release date December, 2015.
