“Eleven years after the terrorist attacks of Sept. 11, 2001, the Government Accountability Office has released a report saying that hospitals have been negligent in securing the radioactive materials they use to treat cancer patients, potentially putting the materials in the hands of terrorists who could use them to make a dirty bomb.
While authorities have identified no specific plot or target for this 11th anniversary of 9/11, the GAO, the investigative arm of the U.S. Congress, has warned Congress about lapses in hospitals, many of which routinely use equipment containing these radioactive materials.”
