The Goiânia Accident (1987)
Why were people from IGR found to be at fault at all? From Wikipedia, it sounds so backwards... like, one of the owners seems to have done everything possible to recoup the radioactive material & warn of the dangers. There's not a word about anything happening to those who prevented the recuperation of radioactive material, only to later fail to guard it. And thieves are only mentioned to say they were not included as defendants.
