Radiation Hormesis? It is a general belief that low doses of ionizing radiation produce detrimental effects proportional to the effects produced by high-level radiation. Over the past decades, however, some pioneer scientists have reported that low-dose ionizing radiation is not only a harmless agent but often has a beneficial or hormetic effect. the body responds to radiation by activating repair mechanisms. Supposedly, the activation of these repair mechanisms causes us to become more effective in dealing with the consequences of free radicals.   [Luckey T.
