Does anyone have a sense for how significant of a dose of radiation this person got?

Not at all. My scintillating counter will do 300 cpm as background. The most concerning thing here will be the ingestion of the water. Even low level emitters can be very bad when the are inside the body

Knowing nothing about nuclear reactor design, why would there ever be a dangerous pool that people could walk by that wasn’t covered? Hard to believe it’s like some kind of Bond villain complex with open pools everywhere. This must have been in the course of some kind of servicing that required opening something that normally stays closed?

Because it's generally speaking, not that dangerous. Water is very good at blocking radiation. That's part of the reason why the pool is filled with it to begin with.

I personally consider an area dangerous if I need to undergo radiation decontamination after entering it, continue emitting radiation after decontamination, and need to seek medical attention. Maybe the nuclear regulatory bodies have differen definitions?

I have SOOO many questions, and this report answers SOOO few of them.

My question is what happened between when they went in the water and when they got off-site medical treatment. 7 hours seems like a long time. Is there on-site medical that would be doing something during that time?

Anecdote: My house mate in grad school was working in a national lab when an experiment caught fire and the fire consumed a certain amount of radioactive material. (Tiny little buttons used for calibrating detectors). He was on shift and was the person who discovered the fire and pulled the alarm.

Among other things, he had to sit inside an enclosure made of scintillator material for a period of time, to make sure he wasn't contaminated. Then he also got blood tests for heavy metals etc. They pretty much went by the book for all of these tests.

Also, the facility is the only place that's equipped for this kind of situation.

> Non Emergency I guess in a nuclear reactor there is a lingual shift and the word emergency cant be used for just any old 911 call. Like how Australians apparently call a jellyfish bite "uncomfortable"

Aussie surfer here, the stings typically are uncomfortable. Some of the deadlier ones can be close to painless and only result in itching and result in you dying from respiratory failure 24 hours later. Others are downright painful with even strong opiate based pain killers struggling to cut through the pain.

Hahaha eeesh that 2nd sentence took a turn
