President-Elect, Health Physics Society
Dr. Nolan Hertel is a Professor Nuclear and Radiological Engineering at Georgia Institute of Technology. Hertel has been a member of HPS since 1981 and has served the society through his participation on the board of directors and on various Society committees. In 2016 the society presented Hertel the HPS Distinguished Scientific Achievement Award, recognizing his contributions to the scientific field of radiation safety and for his accomplishments regarding the practice and advancement of the profession of health physics.
Hertel earned his BS and MS degrees in Nuclear Engineering from Texas A&M University and his PhD from the University of Illinois at Urbana-Champaign. He previously served as a faculty member at the University of Texas at Austin. In 1993, he moved to the Georgia Institute of Technology to join what was then the Nuclear Engineering and Health Physics Program.
While at Georgia Tech he has held numerous positions including Chair of the Health Physics and Radiological Engineering Research Group, Radiological Safety Officer, Director of the Neely Research Center, and Research Fellow of the Sam Nunn Security Program of the Georgia Tech School of International Affairs. Currently in addition to his faculty position, he holds a joint faculty appointment in the Environmental Sciences Division at Oak Ridge National Laboratory and currently is the Acting Director of their Center for Radiation Protection Knowledge.
Topic: Doses to Members of the Public from I-131 Patient Release
The US Nuclear Regulatory Commission tasked the Center for Radiation Protection Knowledge at Oak Ridge National Laboratory to perform calculations of doses that may result from exposure to patients who had been administered I-131. The main purpose was to compare the results of dose calculations performed under the simplifying assumptions currently used with those performed without such assumptions, using more realistic irradiation geometries. Tissue attenuation using anthropomorphic phantoms and iodine biokinetics were considered in the patient in an effort to improve external dose estimates compared to the point source/target method. The external dose rate estimates were derived using Monte Carlo methods and the PIMAL phantom previously developed by Oak Ridge National Laboratory for the US-NRC. In addition, an internal pathway dose scenario was developed to estimate doses due to a housekeeper in a hotel due to uptake of I-131 from contaminated surfaces and air.
