1 curie is roughly equal to 34 billion becquerels of activity. Radiotherapy machines contain about 1000 curies and can kill you in just a few minutes of exposure.

At 750 million becquerels, that would suggest that every 50000 liters of water contains enough radioactivity (roughly 1000 curies) to produce severe, potentially fatal, health effects in an average person in only a few minutes of exposure. That means that an olympic swimming pool of this stuff could potentially kill 50 people within just a few minutes.

HOWEVER: As water is a good moderator, it would likely take substantially more to produce severe health effects. I don't know enough about radiobiology to make a good judgement call here.

Even the millions/billions listed here isn't really all that much. FBaggins Aug 2013 #23

If there ''isn't really all that much,'' why is it still a radioactive catastrophe 2.5 years on? Octafish Aug 2013 #29

Maybe because there's much more to it than the contamination in this water? FBaggins Aug 2013 #32
