Professor Robert Fleischer publishes article in American Scientist

Robert L. Fleischer, research professor of geology, is the author of a recent article in the July-August issue of the American Scientist titled "Serendipitous Radiation Monitors." The article describes how ordinary solids that just happened to be in the right place at the right time have been used to measure radiation exposures. Two examples are the use of eyeglass lenses to measure exposures of individuals to the radioactive gas radon, and employing glass objects from near where the bomb went off at Hiroshima to find the doses of neutrons. Geology students Steven Hadley, Nick Meyer, and Jonathan MacDonald were co-workers on these projects.
