Both inside and outside of AECL, people had such trust in the Therac-25 machine and its software that they discounted their own powers of observation. For example, in the first case, the medical staff at Kennestone were unable to accept the idea that the patient had suffered more than a minor radiation burn. Nevertheless one of Kennestone’s medical physicists did call AECL to inquire if it were possible for the Therac-25 to operate in a way that would cause radiation overdose, but AECL assured him that it was not, in fact, possible. The details of the accident were not reported to AECL or to the FDA, because the physicians in charge didn’t even agree that an accident had occurred. (Brinkman, 20120124)
