Testing by the U.S. Army Corps of Engineers found no radioactive contamination at a Missouri school that was shut down last month amid fears that nuclear material from a contaminated creek nearby had made its way into the school, Corps officials said Wednesday.
Teams from the Corps' St. Louis office began testing the interior of Jana Elementary School in Florissant, Missouri, and the soil around it in late October, days after the school board closed the school. The closure followed testing by a private firm that found levels of radioactive isotope lead-210 that were 22 times the expected level on the kindergarten playground, as well as concerning levels of polonium, radium and other materials inside the building.
