You keep acting as if it's abusive, but helping people pull themselves out of ignorance isn't abuse... though it can certainly be uncomfortable. Let's take a look at some of your misunderstandings.
So, bananas emit measurable levels of cesium 137?
Nothing "emits" cesium. It's the cesium that does the emitting (in this case, beta particles). The Potassium 40 in bananas (and throughout your body) also emits beta particles. So the comparison is entirely appropriate.
How about other long-lived radionuclides?
Potassium 40 is many billions of times longer-lived than cesium
Is the "natural" radioactivity in bananas lethal at the atomic or molecular levels?
Well... no. But then again, nothing is "lethal at the atomic or molecular level".
You don't mention becquerels, curies, sieverts or millisieverts.
Nope. I went further and compared the activity level for each and gave you the results. Bananas emit roughly 130 Bq/kg while the released water was reported at 24 Bq/L. That's roughly 5-6 times as much.
You don't mention that cesium 137 is lethal at the atomic or molecular level.
Which is good... since I would look pretty foolish making that mistake.
You don't mention that less than a dime-sized piece of cesium 137 can contaminate many kilometers of land.
Well now... that's certainly true. But how much do you think we're talking about here? Let's take Pam's IQ test together, shall we?
They reportedly leaked 1,000 tons of water contaminated with 24 Bq/L. Let's imagine that they did it again the next day... and then again the day after that. Then it just kept happening week after week... month after month... even year after year. After a decade... how many "dimes" of cesium do you think they would have released?
Cesium doesn't weigh the same as nickel/copper, but we'll just take the weight of a dime (a bit over 2 grams) and assume that it's all cesium 137. The specific activity for Cesium 137 is a bit over 3 TBq/g. So a dime's-weight-worth of it would be about 7 TBq.
So it would take several hundred years of daily releases like this to equal a single "dime". Though, of course, you would effectively run out of cesium long before that happened.
Until you can pass those kinds of "IQ tests"... it really doesn't matter much to me whether or not you take me seriously.
