As reported by Science Magazine, a study by Princeton University researchers has revealed that U.S. Nuclear Regulatory Commission (NRC) estimates of the catastrophic consequences of a high-level radioactive waste storage pool fire in the U.S. are dramatically downplayed. The researchers, Frank Von Hippel and Michael Schoeppner, report that nearly 39,000 square miles of land downwind of a pool fire could be contaminated with Cesium-137 at levels requiring mass, long-term (300 years) evacuation. Princeton's calculations are more than three times NRC's land contamination estimate, and the relocation of 18.1 million people is about five times NRC's estimates. Please contact  President Obama and your Members of Congress, urging Hardened On-Site Storage of high-level radioactive waste, as a wise alternative to proposals to rush into parking lot dumps, and the large numbers of Mobile Chernobyl shipments by road, rail, and/or waterway through most states that would be launched. More
