"Software programs are killing people." At the National Cancer Institute in Panama City, five cancer patients died after an overdose of radiation during their treatments. The U.S.-made software that calculated the dosages of these treatments doubled the dosages during treatment of 27 patients. The International Atomic Energy Agency's investigation of the five deaths blamed radiation poisoning, and said that the remaining patients would be at risk for developing "serious complications" from the radiation. Two of the Panamanian technicians were convicted of second-degree murder and are serving four-year sentences in a Panama prison. And the makers of the software, Multidata Systems International in St. Louis, Missouri, deny any wrongdoing.
