In Greek mythology, Promethius brought fire to humankind to better their life and was punished by the gods. Fire is a double edged sword – it both warms and destroys. Promethium is an element that symbolizes that same double edged sword. Promethium is a by-product of uranium fission. The idea of nuclear energy is an attractive thing that may bring great benefit but it could also lay waste if we are not mindful of its danger.
