Most of the big buildings around here are limestone because we have so damn much of it, including all the original buildings at the core of the University of Texas. Once our physics professor brought a Geiger counter into class to put next to the wall and show us that Texas limestone is naturally radioactive, at safe but definitely measurable amounts.
