Iowa Research Suggests Gamma-Ray Spectroscopy May Provide a More Accurate Measurement of Radium


In a paper published online in Environmental Science and Technology Letters, first author Mr. Andrew Nelson, a doctoral student in the University of Iowa’s Interdisciplinary Graduate Program in Human Toxicology, and colleagues examined the effectiveness of several methods of measuring radium levels in FBW. The study was conducted using a 55-gallon drum of FBW from the Marcellus Shale Region in northeastern Pennsylvania. The sample was extracted from a 2,100-meter deep, horizontally drilled well that was hydraulically fractured.
