Experts believe that there could be a simple explanation behind the Department of Defense inadvertently sending out live anthrax samples.
The spores are incredibly tiny and very tough, and the irradiation procedure used to deactivate them might not have killed each and every one, John Peterson, a microbiology professor who works with anthrax at the University of Texas Medical Branch, told NBC News. Anthrax spores are one micron in diameter, and samples could contain 10 billion spores, making it difficult for an X-ray or gamma ray to kill all the spores. "If a procedure kills 99.999 percent of the bacteria, there would still be 100,000 spores left viable," Peterson said. "They are very difficult to kill."
