Exploratory and optimization experiments in the use of in-process isotope neutron sources to produce short-lived intrinsic radiotracers were initiated. Flux determinations using manganese sulfate solutions and indium foils were performed. The maxtmum thermal-neutron flux measured by indium acttvation was found to be 9.6 x 10/sup 4/ n/(cmsup 2/) (sec) for a 10-curie polonium-beryllium source. The peak flux occurred 3.2 cm from the center of the source through approximately 1.6 cm of water moderator. The study of the mechanism of formation of free radicals in polymeric materials was continued. Again, emphasis was placed on an examination of the effects of structure and molecular weight on the efficiency of free-radical formation in acrylate and methacrylate polymers. In addition, the investtgation of tbe potential application of this information to thc development of graft copolymers was continued. (auth)
