Exactly the path I travelled too - used to walk around thinking I am the DATA GUY - look how I handle abstract concepts, untainted by the physical. Now I rather tinker with machinery and build stuff. Ah, hell, fuck that, I just go fishing. And get off my lawn, kids!

You mean the french, that have to buy power from our wind energy, because their bloody plants can't even withstand a summer heat wave and have to be shut down? That nuclear wonderland to our west? Yeah, right... thought so.
And of course you assume those few mSv as a whole-body dose. Nevermind that it bioaccumulates in bone, happily irradiating my marrow. No, it's not the nuclear industry that fucks us up, it is GOVERNMENT REGULATION. Man, I'd love to live in that simple world of yours.
As the saying goes, you are entitled to your opinion, but not to your own facts. Concentrated solar thermal can drive steam turbines, molten salt storage can buffer the nighttime. Here's one tiny, insignificant manufacturer.
You know, the situation at Fukushima does not improve by your attempt to utilize the tsunami victims for your propaganda. Also, no one is going to fall for it, so show some respect.
Stochastic does not mean unpredictable. And the "carpet every inch with solar panels"-thing conveniently leaves out solar thermal, which has an intrinsic storage capacity.
Local-ish, like me, in my hometown 1000 miles from Chernobyl, not being able to collect mushrooms due to Strontium contamination, today? I completely agree that coal has to go, but hopefully, nuclear will be only a temporary solution, to be phased out for renewables in the next decades.
Someone just sold his soul to the PR department. You are lost, mate, eternally. One does not joke with matters like that, matter that were never meant to be dealt with by humans.
Technically, yea, you can precipitate everything and filter. That would take a lot of chemistry, though - better to use an ion exchange resin to get the soluble components bound to the resin. With the volumes we are talking about, you probably gotta construct a whole treatment plant for that. And that takes time. That's why they focus on storage atm, I guess.
While I agree with your sig wholeheartedly, enforcing it by arguing with anonymous sexist troll asshats on/. might not be the best use of your resources. It's a losing battle. The idiot density on this site is scary sometimes.
So, according to your table, the activity of coal ash is in the same order of magnitude as that of ordinary soil or ordinary fertilizer. Equivalent to nuclear waste, yes? Jesus, can't you even read your own links? Who is shilling for what industry here?
The so-called "study", however, did claim that a coal plant *emits* radiation like a dirty bomb. Now it is staying in the bottom ash and gets deposited? What is it now? Here are real data. So, we are seeing 3.5-4.5 pCi/g in bottom ash and 5.8 pCi/g in fly ash. As a comparison - let's look at a banana then 3.5 pCi/g. Coal ash is at average twice is active as a banana. God, yeah, hellish technology. Average soil according to the same site: about 14 pCi/g. It is less bloody radioactive than soil. So, these are the data. Also: Mercury retention in fabric filters is greater than 80%.
You know, in my original post, I pointed out that removing the core and pressure vessel from TMI took about 10 years after a meltdown. That's the highest radiological concern you get when decomissioning a plant. Now, all of a sudden, you pull 30 years out of your arse as normal decomissioning time, just so that this doesn't look bad, and THEN insult me as a creationist? Mate, back to propaganda school. You suck at it.
I'd have to check if there are any isotope-specific papers. Lots of exposure studies have been done in the 50s. I got some papers on the topic at work, but can't get at them now - and I am not recalling the details, to be honest. If you are interested, I can check the data and post here on monday.
Oh my, the new scientist. Wouldn't wipe my ass with that rag. They are cooking up a propaganda paper out of Oakridge that was written in the seventies - AGAIN. Guys, if you don't have any better arguments for nuclear power than bullshit from 40 years ago, you got a problem there. Hell, they are going on about bloody acid rain in there - as if there were any coal plants around in civilized countries that didn't wash out sulfur dioxide. Also, ash filters. Install them.
I don't know how you run your coal plants, but around here, we filter out flyash. Coal is about as radioactive as simple soil, it doesn't really show above background. Gets concentrated a bit in the ash, naturally, but there is no radiological concern. Heavy metal contamination can be high in some coal sources, but usual coal ash is just used as building material - additive for concrete and blacktop. If it contains heavy metals beyond the limit, it is heat treated to glass it to immobilize the heavy metals and used as filler in mining below the water table. If you decomission a coal plant, you blow it up, bulldoze the rubble and it is GONE. Now, if you do not filter the ash out, you get increased heavy metal levels in the soil wherever it gets blown, That, you basically can't clean up. Time for it to vanish depends too strongly on the particular retention properties of local soil, so no ballpark number there. That's why you do all the filtering, though, and don't let it get into the environment in the first place.
We are not talking about pure tritium contamination here, in fact, tritium is probably negligible. Most of the activity comes from dissolved I, Cs, Sr, Tc and whatever gets washed out of the fuel rods. So you got stuff with longer and with shorter half-lives in there.

Show me one incident of a refinery fire that required a decades-long evacuation of thousands of square kilometers, then we talk.

day N+1: pro-nuclear activists claiming their prior statements did never happen
Of course the only alternative to wasting energy like it is going out of style, the American Way, is living in a cave. Holy false dichotomy, batman.

So, heck, yeah - it is just another means of decomissioning? That what you are saying?

His study is based on the *anecdote* about 4 men in total.
The fly ash is filtered out. Nothing goes through the stack. And what radiation are you talking about, the one you pulled out of your arse?
