A banana is radioactive as well. What is the exact negative effect compared to coal?

I hate the banana equivalent dose. It entirely papers over the substantial difference between alpha, beta and gamma radiation, ignores where radioactive substances accumulate in the body and what effect those differences on the actual inflicted damage have. It’s a cheap stunt to dismiss any sort of reasonable debate. If you cite it in defence of any actual nuclear fallout pollution, I personally consider it as proof that you’ve just disqualified in this discussion.

I think you've somehow ended up with the exact opposite understanding of what the banana equivalent does is intended for. It serves to call attention to the fact that measurable radioactivity is not necessarily dangerous enough to worry about, and that an actual safety assessment requires more detail than just pointing out that something is radioactive.

Similarly, pointing out that there is a measurable amount of Cs-137 in wildlife in Germany is not a statement about safety. More context and more quantification is required to make it anything other than sensationalism.

That’s what it may have been created for, but it’s not what it’s used for.

It’s been quantified and researched and the recommendation is still that one should control its intake of game meat and especially mushrooms from these regions because the CS-137 concentration can (depending on the kind) have multiples of the legal maximum (1) It’s perfectly safe to occasionally eat normal amounts’ but dismissing it as bananas is not appropriate.

I'm not seeing anyone here trying to imply that it's as safe as bananas, but I do see a comment that tries to imply that the degree of Cs-137 contamination is about a thousand times higher than safe levels (300 years, ~30 year half-life). As your citation shows, the worst measurements of bioaccumulated Cs-137 in recent years have been merely 2-3x safe levels, with older outliers having been 10x safe levels.

That’s not what the comment says. It says that it will take 300 years for all the CS to vanish. But even by your interpretation, a response along the lines “This is a perfectly safe amount of radiation by all standards (or, as my comment: This is perfectly safe for limited consumption) would have been substantially better than pulling out the BED and trying to shut the discussion down with it. Note that the line you quote from my comment includes a wordplay on the BED (“bananas”)

> It says that it will take 300 years for all the CS to vanish.

Yeah, and that's an obviously wrong statement when taken literally. So which is the more reasonable interpretation: that he was trying to say that the danger from the Cs-137 would take 300 years to vanish, or that he was providing a number that's not just wrong, but also irrelevant and misleading?

Look, you’re moving goalposts. I criticize the usage of the BED in trying to make that point. I don’t intend to discuss whether the dosage is dangerous or not, or whether the point that levels still are substantially increased was well made or even appropriate.

Not only that but, you would have be constantly exposed by constantly eating bananas. And even at one banana/minute you would only be exposed to an amount of radiation that is lower than living on earth.

If BED was a thing, banana plantation workers would all radiation poisoning.

Don't you think it's a little short-sighted to think just in categories like black and white (i.e. coal and nuclear energy)? Coal is also very bad in my opinion. We should work towards using more renewable energy and its research. And what about reducing energy consumption?
