Abstract The current status of research on theadaptive response induced by low level exposures to environmental agents is brieflydescribed.Emphasis is given to the characteristics of the dose-response and time-responserelationships of adaptive response induced by extremely low dose-rate ionizingradiation.Recent advances in the mechanistic studies of adaptive response to low levelionizing radiation is analyzed.A discussion is given to the outlook of application of thescientific data concerning the adaptive response induced by low level environmentalagents.Suggestions are made for further research in this field.
