[Closed] The Long Shadow of Chernobyl

if the questions I posed have been answered will you please copy and paste them?

Just when I thought you could not get worse

Ok i am going to runa sweep stake on this i am going for you having been answered 23 times and claimin got have not been answered 25 anyone else
PS 1 more page before closed as well

direct lift from the NEA numbers. 80 years worth of KNOWN reserves as that fits my view . I am going to ignore the rest of the quote about how much they can reasonably expect to find once they explore other potential sites as frankly that part of their view does not fit with my view so I shall just ignore it and pretend it is not part of their view

Dont challenge me I shall mock your faith whilst bigging up my simple logic if you do NOW ANSWER MY QUESTION BY AGREEIN WITH ME

Jesus wept pathetic - you dont like the amswers that is your problem

I note wyou dont comment on your own refusal to even answer the question and ewhen you eventually did answer all you said was that you were refusing to answer. Super work of comedic genious or shocking lack of self awareness?

You are going to claim the edinburgh defence soon aren't you as franky this is getting more and more tragic by the post.

I am leaving the thread before the mods express their displeasure in me again.

I could answer your question by saying " new technology will come on line meaning this problem will disappear"

you seem to find that an acceptable answer for the questions I ask about nukes 🙂

So, renewables. At the moment it makes up a teeny weeny proportion of power generation. How will these be expanded to meet the shortfall with no coal or nuclear (and longer term gas too).

How many windfarm, Solar installations, geo-thermal stations, hydro electric, wave thingies and anything else will we need?

Where is this all going to go and what has to be sacrificed to enable this? Do we give up prime farm land for this and then do we start to go hungry?

Ah, a daily mail reader!

apparently its acceptable to answer:-

"new tech will come on line and make it all work in a satisfactory way"

Where did this word "known" come from. As a geologist I'd rather quote "proven", "probable" and "possible". After digging about a bit on the Net, for uranium those correspond to 80+ years, 2-600 years and very approximately 3000 years. Look at the evolution of "proven" reserves for oil and gas over the last 50 years and you'll see that we are now running on what was "possible" back then.

So, without (at current technological levels) nuclear, when the sun goes down, it's going to go dark & quiet.

Ironically, it's also going to be darker for longer in Scotland 😆

Interesting news on the BBC site

http://www.bbc.co.uk/news/uk-scotland-tayside-central-17445479

A US power company is planning to build a coal-fired power station at Grangemouth, BBC Scotland has learned.

The proposed plant would be built at the Port of Grangemouth, on the Firth of Forth, west of Edinburgh.

C02 emissions would be captured and piped to St Fergus in Aberdeenshire, before being stored deep under the North Sea.

Sound familiar?

So after "not enough rare earths" and "not enough uranium", Wrecker now adds "not enough land space for renewables".

Yes it does sound familar, Pied, and will probably go the way of the previously announced, much vaunted, and cancelled capture and storage projects.

Zokes - so no answers again then What a suprise.

PMSL! Well, you've cheered me up this morning with such an insightful and decisive argument winning post 😆

Australia has been about for billions of years, it's outlived the dinosaurs and god knows what else. I'm pretty sure the place will outlive humanity without changing much. Seeing as I spend far too much time travelling around it for work, I can assure you it's pretty bloody big too. So, if we're looking for somewhere that's large enough (it was mainly formed in the early archaean age - the clue's in the name) and also geologically stable, I'd suggest I'm sat on it right now. Ironically, it's also where most of the stuff comes from in the first place.

As for vitrification: well, I've never head of glass dissolving. I accept if you leave it somewhere windy and dusty it might erode, but deep under ground there's not much wind.

I think you'll find we borrowed this fro you re: wave / tidal on a large and non-environmentally-damaging way.

Well, as opposed to letting this harmful pollution out into the atmosphere, I suppose "just sticking it in a hole in the ground" might be an improvement, if it can be kept there for eternity, seeing as CO2 doesn't decay at all...

Truly EPIC BATTLING guys, mostly TJ tho, the rest of you need to reed that parable about internet arguing and pig wrestling.

Im still after the proof that 10's of thousands died as a result of the op subject. Seriiously TJ, i'd like to see it but I can't find it. Pointers please?

ernie.

The name comes from the ancient Greek "????" (Arkh?), meaning "beginning, origin".

I should like to go on record that neither side of this argument is succesfully making their point.

But do carry on.

There's apparently "plenty of proof", only problem is that TJ is the only person on the planet with access to this, and he won't share it with anyone else.

But do carry on.

Well, I'm unsure what's meant by this. TJ has made several wildly inaccurate statements but failed to back them up when challenged. He's also asked several questions which have been answered by myself and others many times, usually on a point-by-point basis for easy digestion. I'm not quite sure how more plain I can be without drawing pictures or acting it out through the medium of mime 🙄

I appreciate that the subsequent head banging against the faith-healer's brick wall probably isn't very easy reading for the impartial, but this is what happens when TJ closes his eyes but carries on typing. Have a look on other threads with the tag "TJ Argues" for proof of this.

I'd actually quite like to carry this discussion on with Edukator and others in a much more civil manner, only without installing Chrome and Killfile for TJ, I'm not sure that can ever happen on this topic.

Thank you I_Ache, but what I was confused by was this :

Australia has been about for billions of years

.....it was mainly formed in the early archaean age - the clue's in the name

I wasn't aware that what we know as Australia has been about for billions of years, nor do I see a clue in the name, other than the fact that both words contain the letters A and R.

Of course I could very easily be missing something but I have no idea what it is.

The clue's in the name of the geological age in which it was formed i.e. the Archean. This is what I meant.

I believe the etymology of the name Australia is from the latin word for southern.

I wasn't aware that what we know as Australia has been about for billions of years

Well, unlike TJ facts, this is an actual scientific fact 🙂 Every day's a school day an' all....

Oh ok, I thought you meant there was a connection between the words Australia and Archean, my misunderstanding. I also thought Australia was a bit newer/more recent.

Some of it (Victoria in particular) is much newer, but what most people associate with Australia i.e. the red centre is certainly of the order of billions of years old, which to a human whose life expectancy is about 80 years, whose modern civilisation has only been documented for around two millennia, and whose species as a whole has only been around for 50,000 years, is an incomprehensibly long time. The Gawler Ranges (about 800 km NE of Adelaide) are reckoned to be amongst the oldest rocks on the planet.

I suppose "just sticking it in a hole in the ground" might be an improvement, if it can be kept there for eternity, seeing as CO2 doesn't decay at all...

It can be kept there for an eternity, and decay doesn't come into it, but then you already know that?

It can be kept there for an eternity, and decay doesn't come into it, but then you already know that?

If you can keep something that wants to be a gas in a hole for eternity without it escaping (and I am happy to believe the science on this), then presumably you can also keep something that is a solid, and that there will be much less of (e.g. vitrified nuclear waste) there too? Or am I missing something?

Put glass in humid and possibly corrosive conditions and it weathers quite fast. The next time you visit a cathedral with original glass have a look at the state of it. However, I examined samples of glass from the surface of the moon and they are in perfect condition despite being billions of years old. The trick then is to keep the glass dry and away from potentially corrosive conditions.

If you remember governments were trying to cinvince us (especially the French) that underground tests were safe as the whole lot would end up as stable glass due to the high temeperatures. Well [url= http://cyberplace.org.nz/peace/nukenviro.html ]that hasn't beeen the case[/url]. I know that link is biased but France 2, our state propaganda, has also shown programmes demonstrating that the atols are leaking radioactive isotopes.

Radioactive glass needs to be kept clean and dry or it weathers and releases radioactive material. Australia does indeed offer some of the best disposal sites on the planet, but why should a country that doesn't use nuclear power and has already been irradiated by foreign testing take the stuff off us?

because they'll make a lot of money if they do so.

they already make a lot of money digging stuff out of the ground, some of which is quite nasty, this way they can make even more money by filling a few holes.

or not, their choice.

but why should a country that doesn't use nuclear power and has already been irradiated by foreign testing take the stuff off us?

Money. It's an industry, isn't it.

Gotta say, this thread is awesome. Please carry on, it's stopping me getting bored on a middle eastern bank holiday.

Interesting stuff Edukator. I've just spent the past 10 mins or so poking Web of Knowledge for papers discussing leaching of nuclear materials from test sites, but I have to say I couldn't find anything. Admittedly this is partly due to the fact that both the search strings "atom*" and "nuclear" have meanings other than power or explosions in science. So just because it doesn't exist, doesn't mean the evidence isn't out there.

I'd happily accept that such research may well be carried out by state science organisations and as such not published in peer-reviewed literature, which doesn't help. One thing to bear in mind is that the force of a nuclear explosion at the test site would obviously disturb the geology somewhat, and this wouldn't be the case in a repository, so it's not a perfect comparison.

But, assuming it can be in some way encased in a material that isn't vulnerable to humidity, (PTFE might be an idea), sticking it in a hole does seem like a logical option.

The topic of an international repository does crop up from time to time down here, as does nuclear power. We do after all have the potential to export large amounts of uranium, why not make money selling it, then make even more taking it back! Also, we have one shut down and one operating research reactor, as well as numerous hospitals and research facilities (including my own) that generate various levels of nuclear waste. So as a country, Australia does deal with some amount of HLW waste already (not to mention the tons of VLLW from digging up U in the first place).

Lots of different studies giving lots of different answers.

One aspect to be considered is that is there a threshold below which radiation does not cause deaths? Some say there is, some say there isn't. Makes a big difference to the numbers of predicted deaths.
( http://en.wikipedia.org/wiki/Linear_no-threshold_model ) I believe this linear no threshold model is the most likely and numerous scientific bodies do as well.

UNSCEAR has conducted 20 years of detailed scientific and epidemiological research on the effects of the Chernobyl accident. Apart from the 57 direct deaths in the accident itself, UNSCEAR predicted in 2005 based on Linear no-threshold model (LNT) that up to 4,000 additional cancer deaths related to the accident would appear "among the 600 000 persons receiving more significant exposures (liquidators working in 1986–87, evacuees, and residents of the most contaminated areas)".[107] Later this number was revised slightly up to 5,000. The number of excess deaths among 5 million people living in the less contaminated areas is estimated at 3,000–5,000. The number of excess cancer deaths worldwide (including all contaminated areas) is approximately 27,000 based on the same LNT.[108]

That may well be the most rigourous but almost certainly a pessimistic view.

[b]27 000 deaths[/b].

Teh torch report gives 60 000

"Chernobyl: Consequences of the Catastrophe for People and the Environment" published by the new york academy of sciences gives a figure of a million.

Given this to say tens of thousands of deaths is not unreasonable I believe

Lots more references from Wiki.

http://en.wikipedia.org/wiki/Chernobyl_disaster#cite_note-Union_of_Concerned_Scientists-109

Edit - the 27 000 prediction in not unescar - its a prediction made from using their methods and projecting them over the rest of the irradiated area.

Teh 5000 deaths unescar predicts is only in the most contaminated areas

Aha -

~zokes - are you now accepting that actually no one knows what the effects of burying waste for thousands of years is?

IE there is no solution to the issue of high level waste.

If you have one you really should apply for your Nobel prize.

Genius TJ and herr zokes going head to head, some perverse form of perpetual motion has been created. This will last forever 😆

Na - I only wanted to give an answer to a question I was directly asked and couldn't resist another poke and Zokes for " chuck it in a hole and forget about it" with no detail given at all.

I have had enough of it - its clear the pro nukes will simply continue to evade as there is no answers given or even known to the pertinent questions

I'm another "no threshold" supporter that puts the Chernobyl premature death rate in thousands.

On the nuclear waste front though there are lots of alternatives:

Burial in subduction zones: in the ocean floor if international agreement can be reached or in a continental zone if not.

Very deep burial using oil drilling techniques to reach geologically capped structures.

"Dilute and disperse" is a technique used for lots of pollutants. Mix high level waste with uranium mining waste and put it back where it came from (if Zoke's countrymen/women are prepared to take it).

Burial in tunnels in safe geology. So far the safe suggestions have proved less safe than originally thought and the projects I was aware of have been cancelled.

There's also the shoot-it-into-space idea but I'm trying to keep this sensible.

I'm another "no threshold" supporter

This is a huge bone of contention amongst scientists, as it's impossible to prove one way or the other. As the golden rule of HSE is to err on the side of caution, the official line is often to assume the model is linear unless evidence presents itself to the contrary i.e. the null hypothesis. You could write several health physics PhDs on this and not get close to the answer. Any scientific report on Chernobyl worth reading will certainly have discussed these issues in some depth, even if this isn't apparent from the summary.

There is actually lots of rational argument against the LNT model though. People are exposed to ionising radiation every day from UV the sun, from potassium-40 in everything they eat, from radio-medicine, x-rays, from cosmic rays when flying. The latter is usually the greatest source of radiation exposure for people who travel a lot, yet I'm not aware of any peer reviewed evidence to substantiate that air crew are more at risk of cancer than any other demographic.

I actually work with radiation (14C to trace carbon through ecosystems) on a daily basis for my research, and the maximum dose that I'm allowed to record on my dosimeter per year is 20 mSv. For medical staff I believe it's around 5 mSv, and for the general public, it's 1 mSv. All these are thresholds. If the LNT hypothesis was correct, these thresholds would be 0 mSv.

However, you are exposed to 0.007 mSv for every hour you're on a plane. So to get the maximum 20 mSv a radiation worker is allowed to be exposed to in a year (and not be considered at risk - that's the important bit, i.e. not 0 mSv), a pilot would have to be in the air for 7.8 hours a day every day of the year assuming they work 365 days a year. Now I don't know much about air crew shift patterns, but assuming they work 200 days a year, and are in the air either at rest or working on long haul flights, that's only 14 hours a day for 200 days, which sounds quite reasonable for someone on a long-haul route.

You would assume that as these different thresholds exist for the general public (and curiously given what I've just presented, pilots etc) vs me indicate a level of risk then. If so, and if air-crew receive around 20x the maximum permissible annual dose from anthropogenic radiation for non-radiation workers, why is there no strong evidence highlighting that they are 20x more likely to die from cancer than the general public? If the LNT model holds, there should be good evidence of this, and there isn't.

And on another note, anyone worried about contamination of groundwater from energy production had better have a read about CSG and fracking, then stop using gas asap.

There is evidence linking low levels of naturally occuring radiation and increased cancer risk, Zokes. I read something about it recently. I'll Google "naturally occuring radon and cancer" later but I've got some investments to look after this morning (including some in "développement durable" 😉 ).

I have stopped using gas, Zokes, and as a geologist that used to work for a water company talk of hydraulic fractures raises my blood pressure.

There is evidence linking low levels of naturally occuring radiation and increased cancer risk, Zokes.

Yeah, I'm aware of this - yet another reason not to live in Aberdeen 😉

So clearly it's a very interesting point, but as the sievert is a very good unit incorporating both the energy of the absorbed dose (in greys), and the relative biological efficiency of each type of radiation (i.e. you may receive a large number of Gy of one type of radiation, but it may not be as dangerous for what ever reason than a lower Gy dose of another type).

So comparing between radiation types in Gy is impossible, but doing it in Sv is equivalent. Therefore, assuming the LNT model holds, long haul pilots should be more at risk from cancer than the rest of the population. But yet, I'm not aware of any research demonstrating this to be true.

I need to have a read up on the exposure in Sv of these 'cancer clusters' to Rn before can say anything else on that topic. And right now, I really need to read up on what I should be doing!

Anyway, I still want proper answers to my questions!

I cannot see any option other than to, at the very least, 'top up' electricity generation with nuclear given what's possible today.

So, given that coal & gas will run out and/or become prohibitively expensive to extract, then what will we need for power generation that could realistically meet the demands of today's society? 'Green' power generation is all very well, but I'm yet to be convinced that it can be anything like a viable alternative yet

ALARA As Low As Reasonably Achievable

Stochastic Effects

Page 15

"The relationship between the probability of the occurrence of a stochastic health effect (the response) and the level of exposure to radiation (the dose) at the low levels of radiation exposure routinely experienced at work or in the environment is assumed, for the purposes of radiological protection, to be linear no-threshold (LNT)
– put simply, the response is assumed to be directly proportional to the dose with no threshold dose below which the effect does not occur. This approach is taken because it is believed to be prudent and so is likely to err in the direction of caution; it is also an approach that has the considerable merit of practicality for those managing radiation protection. The commonly used shorthand statement “There is no such thing as a safe dose of radiation” derives from this assumption of no threshold dose for stochastic effects, but is a distortion of the LNT approach because it equates “safe” with “no effect at all, no matter how small”, which is not correct –
it is the level of risk upon which a judgement is made as to whether or not an exposure is safe."

Cheesyfeet 🙂

For me it is to look at the countries energy consumption totally and to make saving where we can - and there is a lot possible.

it will be hard to generate even slightly lessor amounts of electricity without nuclear and reduce co2 output at the same time but there are huge savings to be made elsewhere to offset this

We also have plenty of coal.

Look at some of the work the green party has done on this.

Energy efficency, combined heat and pwer, microgeneration, insulation, heat managements, street lighting, illumination of public buildings etc etc

it simply needs the political will and an acceptance of the fact that we cannot reduce greenhouse gas production without altering lifestyles.

So in otherwords there is no viable alternative as it stands today then? If we turned off nuclear, coal & gas right now, then the UK stops.

Obviously energy consumption is a key issue, and needs to be addressed, but unless there's some key increases in energy generation efficiency, then our kids can look forward to evenings playing parlour games by candlelight!

Having said that, the pace of technology advance is astonishingly fast these days, so I'm very confident that it will be all instant cups of tea from the arm of the sofa whilst they are watching the latest blockbuster on the hologram wall!

Obviously energy consumption is a key issue, and needs to be addressed

This.

The trouble is though, people don't like being moaned at to do things by their government. They dislike it even more when they are being forced to do things by economic penalties such as taxes. They dislike it even more when the tax is to try to prevent something they don't even believe is happening or our fault.

The trouble with disliked governments is that sooner or later, they usually get booted out. The alternative usually gets voted in because they promise to repeal or fix whatever the previous government did to piss everyone off.
