On Thursday, April 4th 2019, the U.S. Government Accountability Office (GAO) released a report on Radiological Material Security. Report experts along with the National Academies of Sciences found the US Nuclear Regulatory Commission does not consider all relevant factors when considering the effects of a dirty bomb. In fact, a large radiological dispersal device (RDD)could cause about $30 billion in damage and 1,500 causalities in the evacuation.
