I'm struggling to understand if this is sarcasm or not.
We are oncologists. We treat cancer. With radiation. We are not hazmat teams. If in the event of reactor explosion or bomb dropping, you stick around to triage exposed patients just so you're not seen as a therapist in the doctor lounge, more power to you. I'm running with everyone else, and would be whether or not I knew I'd die within 2 weeks due to massive GI fluid loss at 6 Gy. I don't think surgeons are required to learn the outcome of every blade related injury/accident through history. I guess, if you somehow give someone an unplanned TBI exposure it may be embarrassing to have to do a quick lit search to figure it out, but that hardly seems like your greatest concern in the situation.
EDIT: I've been called once on something tangentially related to this. After an I-131 treatment in nuc med, a patient wet their bed. The staff took the urine soaked sheets, put them in the normal bag and the linen company took them away. A couple hours later, someone realized this was the wrong thing to do. For some reason, they paged me. Unfortunately, nothing in my oncologic training allowed me to offer them advice on this radiation/linen based accident beyond what a lay person would. Contact the RSO. Contact the linen company.
