Abstract
ONE of the theories proposed for explaining the protective role of certain substances on animals submitted to a lethal dose of ionizing radiation involves the capture of free radicals by the protective compound (scavenger action). As a consequence of this process the compound is chemically modified in the biological structures where it happens to be, which then survive the irradiation. If such a theory is correct a certain degree of correlation would be expected between the protecting activity of a substance and its lability towards radiation, unless a catalytic mechanism is involved.
