George Samuel Hurst (13 October 1927 – 4 July 2010) was a health physicist and professor of Physics at the

Elographics.[1][2]

Early life

Hurst was born on 13 October 1927, in the rural town of

brain aneurysm and was buried at Oak Ridge Memorial Park.[4]

Education

Hurst attended high school at

M.S.
degree in physics. During registration in UK, he met Rufus Ritchie. Ritchie became a longtime friend and the two worked on several projects together. After graduation, they both went to ORNL. 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."

Work

In 1948, Hurst was recruited by

Health Physics Division. His starting salary was $325 per month. He made significant contributions in the development of radiation detectors and instrumentation, neutron dosimetry and spectroscopy, and field sample analysis. While working at Oak Ridge, he earned a PhD in physics from the University of Tennessee in 1959. In 1966, Hurst accepted a position at the University of Kentucky as professor of physics.[6]

Hurst and the team of L.J. Deal and H.H. Rossi performed gamma and neutron radiation measurements at the Nevada Test Site during Operation Upshot–Knothole for the Atomic Energy Commission.[7] For Operation PLUMBBOB, Hurst was again asked to participate along with Ritchie at the Nevada Test Site to collect radiation dosimetry data for human exposures during the tests.[8]

In the 1960s, Hurst along with L.B. O'Kelly, E.B. Wagner, J.A. Stockdale, James E. Parks, and F.J. Davis investigated

time-of-flight electron transport in gases. The group utilized ethylene, water vapor and hydrogen to study and determine time-of-flight electron diffusion coefficients and electron drift velocities for these gases. Hurst led efforts to investigate time-of-flight of electron transport in atomic and molecular gases.[9]

In the mid-1960s, Hurst pursued researches that involved electron swarm measurement, swarm‐beam techniques and swarm drift to determine electron capture cross sections in heavy water, chlorobenzene, bromobenzene, ethylene and ethylene mixtures.[10]
