Radiation hormesis: an ecological and energetic perspective.
Organisms in natural habitats are exposed to an array of environmental stresses, which all have energetic costs. Under this ecological scenario, hormesis for ionizing radiation becomes an evolutionary expectation at exposures substantially exceeding background. This conclusion implies that some relaxation of radiation protection criteria is worthy of serious consideration.
