George Samuel Hurst (13 October 1927 – 4 July 2010) was a health physicist and professor of Physics at the University of Kentucky.
In 1959, Hurst was awarded a Ph.D. in physics from the University of Tennessee with a dissertation titled "Attachment of Low-Energy Electrons in Mixtures Containing Oxygen."
In 1948, Hurst was recruited by Karl Z. Morgan and landed a research position at Oak Ridge National Laboratory (ORNL) in the Health Physics Division.
He made significant contributions in the development of radiation detectors and instrumentation, neutron dosimetry and spectroscopy, and field sample analysis.
Rossi performed gamma and neutron radiation measurements at the Nevada Test Site during Operation Upshot–Knothole for the Atomic Energy Commission.
Hurst led efforts to investigate time-of-flight of electron transport in atomic and molecular gases.
