Abstract

The formation of iron oxyhydroxide nanoparticles under gamma irradiation is a process in the infancy of its understanding. Herein we present work to describe how initial iron concentration and pH impact the growth of radiolytically formed nanoparticles. These results can be used to better understand the activity transport processes occurring within a reactor environment which may pose both environmental and safety concerns. Preliminary results suggest that the final particle size is proportional to the initial dissolved iron concentration, while experiments probing the effect of solution pH are ongoing.
