Abstract
FREE radicals formed in biological materials by ionizing radiation may be detected under the proper conditions by paramagnetic resonance techniques. Possibly such free radicals contribute, directly or indirectly, to the radiation damage suffered by living organisms. The various chemicals which have been found to increase the survival of organisms subjected to large doses of radiation may provide protection by action on the free radicals or by some more direct action on the substance of the organism. This report describes experiments made to see if paramagnetic resonance detection of free radicals could be used to study chemical protection against ionizing radiation.
