Web Home: Radiation and Radon from Natural Stone W.J. Llope Rice University, Houston, TX

Houston KHOU Channel 11 aired a news story during the 10 p.m. broadcast on May 7, 2008 that investigated the possible dangers from natural stone countertops in homes in the Houston area. I contributed some on-air comments, as well as a short write-up. I have a dedicated gamma-ray detection system and will be using it to gather detailed radionuclide identification information from as many countertop stone samples that I can find. This page is the web home for my work on this subject.  So check back periodically! (& refresh this page in your browser if you've been here before!)
