| Research Interests
Radiation effects in condensed phases are due to complex interactions
between the transport of energy, the decomposition of medium molecules,
and the diffusion and reaction of transient species. The program
is multidisciplinary, ranging from probing the fundamental physics
and chemistry associated with the interaction of radiation with
matter to examining the practical consequences of that radiolysis
in biology, medicine, and engineering. Short-lived species and their
kinetics are determined experimentally in the radiolysis of water,
organics, and polymers with a wide variety of radiation types and
energy using the facilities of the Notre Dame Radiation Laboratory
and the Department of Physics Nuclear Structure Laboratory. Interfacial
radiation effects involving the transport of energy and reactive
species through heterogeneous boundaries are being explored for
identification of the underlying mechanisms and for application
to nuclear reactor technology and the environmental management of
radioactive waste materials.
