We clarified that adequate oxygen stress induced by low dose radiation activates not only chemical biological protective function, such as induction of the synthesis of SOD, GPX and HSP70, but also the biomembrane function, such as enhanced membrane fluidity and ATPase activity. It is possible that activation of these mechanisms alleviates in vivo oxidation injuries resulting in alleviation of pathologic condition, such as symptoms of hepatopathy and diabetes mellitus. Namely, adequate activation of the functions of the living body by low dose radiation can contribute to suppressing aging and to preventing or reducing active oxygen species related diseases which are thought to involve peroxidation and have been regarded as the diseases for which radon spring water is an effective treatment. Clarification in detail of the mechanisms of these phenomena is required to understand the effects of low dose radiation on the functions of the living body, including adaptive response.
