Dr. Nolan Hertel


NASA has proposed new models for radiological risk assessment with significant revisions that are based on new epidemiological data and radiation biology results. This has been translated into revised specifications of quality factors in terms of track structure concepts that extend beyond LET alone and will require identification of charge, Z, and velocity, , of the incident radiations. This talk will discuss the implications a revised Q value has on existing radiation instrumentation in space, including instrumentation for neutron dosimetry and detection.


Dr. Lawrence Heilbronn is an assistant professor in the Department of Nuclear Engineering at the University of Tennessee. He received his Ph.D. in experimental nuclear physics from Michigan State University in 1991. Before coming to the University of Tennessee in 2008, he was a staff scientist at Lawrence Berkeley National Laboratory. Dr. Heilbronn has over 20 years of experience in space radiation physics, with a focus on shielding and neutron production in space. His other research interests include isotope production, medical physics, and radiation detection.
