Radiation disaster response

You are the Nuclear Medicine Tech working at the local hospital. It is 4:00pm when you hear over the hospital public announcement system. “Disaster plan external has been initiated.” You hear from the Radiation Safety Officer that a nuclear device has been detonated at the local LA fitness gym. You are called to lead the response since the RSO is 2 hours away.

Describe what and how a local hospital should respond to this type of scenario.
