John Harvey, Ph.D., DABR, CHP

Director of National Technical Operations & Chief Medical/Health Physicist

John Harvey


Prior to joining West Physics, Dr. Harvey completed his Ph.D. at the University of Michigan in health physics. His research includes the accuracy of thermoluminescent radiation dosimeters in practical applications, computerized glow curve analysis, the effects of radon on radiation detectors, and reliability of pocket ionization chambers. He has also participated in research into the computer-aided analysis of radiographic images, which was used to provide radiologists with a computerized second opinion for cancerous lesions in mammography.

Dr. Harvey enjoys teaching basic principles of radiation physics to diverse audiences in order to dispel commonly held myths about radiation and nuclear technology. His teaching experience also covers radiation protection, radiation biology, state and federal radiation regulations, radiation measurement devices, external and internal dose estimation, the principles and history of nuclear energy, and the nuclear fuel cycle.

Dr. Harvey is originally from Plymouth, Michigan.
