Fission energy is radiation that comes from nuclear devices or their radioactive wastes. This type of fission energy does violence to living tissues and speed the aging process. Fission energy ionizes living molecules. Another word for ionization is scramble. Scrambling of living molecules makes life impossible and produces suffering.
Irradiation is another term being touted in the media.
It too can be a verb or an adjective. It describes the 'act' of applying ionizing radiation to living things. In the case of food irradiation, negative ionizing energy is used to scramble food energy molecules and makes them worthless. Eat irradiated food and you will grow old and die early. Radioactive isotopes and waste products from the nuclear industry are the source of the fission energy that is used to 'irradiate' America's food supply.
