Radiation hormesis proposes that radiation exposure comparable to and just above the natural background level of radiation is not harmful but beneficial, while accepting that much higher levels of radiation are hazardous.
The finding that ionizing radiation can (in some circumstances) be benefiical to health goes back more than 100 years - following experiments with X-rays.
The idea of 'Radiation hormesis' - where the source of the ionizing radiation is from nuclear energy, is more recent.
The World's leading nuclear authorities vary greatly in their attitude to radiation hormesis, some maintaining that there are proven benefits and no known risks from very low-dose irradiation - others claimng that radioactivity is hazardous at any level, or that the benficial effects are outweighed by the risks involved.
