Remembering Charles E. Till
Charles E. Till
Charles E. Till, an ANS member since 1963 and Fellow since 1987, passed away on March 22 at the age of 89. He earned bachelor’s and master’s degrees from the University of Saskatchewan and a Ph.D. in nuclear engineering from Imperial College, University of London. Till initially worked for the Civilian Atomic Power Department of the Canadian General Electric Company, where he was the physicist in charge of the startup of the first prototype CANDU reactor in Canada.
Till joined Argonne National Laboratory in 1963 in the Applied Physics Division, where he worked as an experimentalist in the Fast Critical Experiments program. He then moved to additional positions of increasing responsibility, becoming division director in 1973. Under his leadership, the Applied Physics Division established itself as one of the elite reactor physics organizations in the world. Both the experimental (critical experiments and nuclear data measurements) and nuclear analysis methods work were internationally recognized. Till led Argonne’s participation in the International Nuclear Fuel Cycle Evaluation (INFCE), and he was the lead U.S. delegate to INFCE Working Group 5, Fast Breeders.

Within the homeland security and emergency response communities, there is a need for a low-profile system to detect, locate, and identify radioactive sources in real time. Such a system could be deployed for area monitoring around venues for special events. A system was developed at Argonne National Laboratory, called RADTRAC, which is based on a network of radiation detectors and advanced signal-processing algorithms. The initial implementation of RADTRAC did not account for dynamically changing shielding due to crowd movements.An algorithm was developed that utilizes the gamma-ray energy spectrum from each detector to estimate the amount of attenuation and scattering that is present between the source location (a priori unknown) and the detector location in real time. The attenuation and scattering estimations are then included in the maximum likelihood model to significantly improve the source localization solution. Results are presented for several test cases showing the improvement in the real-time source localization solution.This algorithm has been implemented into the current version of RADTRAC such that it now accounts for the effects of dynamically changing shielding and scattering due to crowd movements in real time in order to accurately determine the source location in crowded venues.
