MECHANISMS OF RADIOPROTECTION—A REVIEW
Photochemistry and Photobiology, 1978Abstract— Theories of radiation protection can be considered at both the molecular and biochemical‐physiological levels. Four molecular level protection hypotheses, radical scavenging, hydrogen transfer reactions, the mixed disulfide hypothesis and the endogenous nonprotein sulhydryl hypothesis, probably describe different aspects of the actual ...

Radioprotection by Antioxidantsa
Annals of the New York Academy of Sciences, 2000Abstract: The role of reactive oxygen species in ionizing radiation injury and the potential of antioxidants to reduce these deleterious effects have been studied in animal models for more than 50 years. This review focuses on the radioprotective efficacy and the toxicity in mice of phosphorothioates such as WR‐2721 and WR‐151327, other thiols, and ...

Radioprotection of nonhuman biota
Journal of Environmental Radioactivity, 2008Radioprotection has historically focused on humans with the assumption that human protection confers protection of nonhuman biota. However, there is a need to scientifically and independently demonstrate protection of nonhuman biota. Approaches to address impacts of radiation on nonhuman biota include applying an ecological risk assessment paradigm ...

The Radioprotective Action of Parathyroid Extract
International Journal of Radiation Biology and Related Studies in Physics, Chemistry and Medicine, 1961SummaryThe protective action of a single post-irradiation injection of parathyroid extract in x-irradiated rats has been confirmed. The effectiveness of the extract (as a difference in survival percentage) was greatest in rats exposed to 800 r of x-rays.

The British Journal of Radiology, 1979
The suggestion by Gregory (1978), that the radioprotective effect observed by O'Connor et al. (1977) of vitamin C on hamster ovary cells irradiated in vitro is due to scavenging of solvated electrons produced in the cell by the radiolysis of water, raises the interesting problem of how, in general, radiation chemical knowledge can be applied in the ...
