Scenario 1   (Instructions) 1) In this RDD (dirty bomb) scenario, which of the following statements most accurately describes the casualties that might be expected? Hundreds of patients with combined injuries from significant radiation exposure and traumatic injury may present to hospitals. Since EMS follows strict protocols requiring patient decontamination prior to transport, few patients will need hospital decontamination. The majority of patients will arrive by taxi or in private vehicles rather than waiting at the scene as directed by first responders. Decontamination will be mandatory for all patients arriving at the hospital due to wide dispersal of radioactive dust particles. None of the above.
