Unfortunately, it also provided no useful information quantifying the statements.
Maybe there is a problem elsewhere, maybe the pool is contaminated, maybe the sensor used is very sensitive and 300 cpm is not as concerning as it would seem.
It sure would be nice to have actual data, wouldn’t it?
The reactor cavity water is usually moderately radioactive from activation and small leaks. Not life-threatening but certainly a long term health risk, especially when ingested. That is why the person was advised to seek medical attention.
Regulatory bodies have adopted the LNT (linear no threshold) model and for good reasons. Every exposure increases your likelihood to get cancer eventually. Many things do, such is life, and radiation is one of them.
It was deactivated and being refueled, so likely something leaked somewhere. But that should be a lot more than a ‘we dunno’ if so - it’s not like it’s not going to be clear from isotopic analysis eh? Or hopefully they at least have some decent spectrum on it.
And it should show up in realtime monitoring of the water, unless they just turned that off.
