UW Medicine itself is not doing well financially (they lost $75 million last year): https://www.washington.edu/regents/files/2018/01/2018-02-B-2...
Harborview was the only profitable hospital in the system. Seattle is the second-largest tech city in the nation and housing prices have grown astronomically, just like in SF. The difference between UW and, say, Stanford or UCSF, is that UW's patient population comes from the WWAMI states. They don't typically treat the young tech works, although I have had a couple older Boeing/Microsoft patients. UW/Harborview patients continue to be mostly low-income Seattlites and tertiary care/trauma patients from the WWAMI states. The UW takes care of poor/rural patients while existing in a wealthy city. It's a unique place to work.
EDIT: I asked my fellow radiology residents about this event
"We had a nuc med lecture on the event! It's super interesting how they managed it."
"We had a separate nuclear medicine lecture on a Tuesday by the woman who helped managed the incident and is responsible for nuclear accidents."
"Was on HMC call that night. Physics lecture on that was useful. Radiation --> reflex call radiologist is a real thing."
"Cool. Honestly they should just reflex call them. I just paged them anyway."
“3.6 roentgens per hour. Not great, not terrible.”
