Brief Biography

Kathryn Higley has held both Reactor Operator and Senior Reactor Operator’s licenses, and is a former Reactor Supervisor for the Reed College TRIGA reactor. She has held research positions at three research reactors including Reed College, Washington State University (Pullman), and Oregon State University. She has fourteen years with Battelle, Pacific Northwest Laboratories as an environmental health physicist at the Hanford Nuclear Reservation and three years experience in environmental radiation monitoring at the Trojan Nuclear Power Plant in Oregon.

She has been a consultant to the U.S. Department of Energy’s Office of Air, Water and Radiation Protection. She is a member of the Health Physics Society and a certified Health Physicist. She has served on National Council of Radiation Protection and Measurement (NCRP) subcommittees and on National Academy of Science committees. She is a member and scientific secretary of the newly formed Committee 5 of the International Commission on Radiological Protection. Dr Higley has been at Oregon State University since 1994 teaching undergraduate and graduate classes on radioecology, dosimetry, radiation protection, radiochemistry, societal aspects of nuclear technology, and radiation biology.

Her research at OSU has included the use of nuclear track detectors for determination of plutonium, americium, and uranium particle size in soils, analysis of the micro-morphological distribution and association of these contaminants with soil structural features; kinetics of radionuclide movement in environmental systems; development of novel methods for estimating radiation dose to non-human biota; relationship of morphological characteristics of radiologically-contaminated surfaces on radiation detector efficiency, and effects of scanning speeds for radiological survey systems on detector efficiency.
