DOSE-RESPONSE RELATIONSHIP IN THE YIELD OF RADIATION-INDUCED FREE RADICALS IN AMINO ACIDS

Journal Article · · Physics in Medicine and Biology (England)
Electron spin resonance studies were made of the production of longlived radicals in glycine, alanine, valine, aspartic acid, and glutamic acid. The yield of radicals as a function of dose was measured, using as a source of radiation 14.3-Mev electrons at a very high dose rate. In all cases saturation was observed at high doses (in the megarad range). The held vs dose curves were analyzed in terms of exponential functions and some possible explanations put forward. Absolute values of the yield per unit dose, as well as the saturation values, were calculated, and possible sources of error in the values are discussed. (P.C.H.)
