As we know, Andrew Bolt has been busy downplaying any danger to both workers and the public from the Fukushima accident, to the extent of wondering whether nuclear physicist Ann Coulter may be on to something with her suggestion that it may be good for people.
He referred to a radiation chart made by the person who writes the comic xkcd. I'm sure many people have seen it.
Tim Lambert criticised Bolt for the "maybe its good for them" post, but then also linked to the xkcd chart.
Now I see that George Monbiot has posted that the accident has not hurt his belief that we must use nuclear to combat greenhouse gases. (You can never quite tell which way George will jump. He badly over-reacted at first to the "climategate" emails as if they were stunningly damaging to the science of climate change. He later calmed down and changed his mind.) But anyway, my point is that he has also linked to the chart.
So, all three think it's a cool chart.
I think they are all wrong, and the issue of contamination of food, water and the seas around Fukushima shows why. As a commenter David COG noted at Lambert's blog:
I'd say it's dangerously misleading. It says nothing about the different types of radiation and how they are delivered.
- A speck of plutonium on your skin which is quickly washed off: not so bad.
- A speck of plutonium inhaled and stuck in your lungs: not so good.
It also says nothing about the very real psychological impacts of radiation.
- give someone an x-ray: no drama
- tell someone the local nuke is spewing radiation out: stress, depression, sickness
Now, this guy is clearly an anti-nuclear advocate, and I see that prominent climate change advocates such as Eli Rabbett are arguing with him:dhogaza:
The chart's specifically about the effect of environmental radiation, not of the breathing in of a radioactive particle of plutonium which then becomes lodged in the lung or the like.
The "effect of environmental radiation" is that it is sometimes breathed in or eaten. The chart therefore gives a misleading impression because it's simply a representation of holding a Geiger counter next to each item.
Also, it starts off with the 'banana dose'. This nonsense is all over the tubes right now - people claiming that because bananas are radioactive that the radiation appearing in Japanese food and water is no big deal. This is bullshit. If you don't know why, read this.
In the context of what is happening at the moment in Japan, that chart is going to do nothing but mislead people in to thinking it's no big deal. It is dangerously misleading.
How much sense does Eli's comment make? David COG pointed out that the chart does nothing to deal with the issue of ingested radioactive particles: Eli says (to paraphrase) "of course they are dangerous because you are exposed longer to them." Well, yeah.David, Eli suggests you go think about the difference between washing off a speck of plutonium and ingesting it. Hint, one is with you longer than the other and so the dose is larger.
The Bunny also suggests that silly boys like you are one of the reasons people in the US are stocking iodine pills to protect against the problems in Japan.
Nope, I have to go with the anti-nuclear activist here: people running around with the xkcd chart without understanding its very major limitations are not really being honest about what a nuclear reactor failure with leaks to the environment is about.
And although people may think I'm spending a lot of time dissing nuclear if I promote it: I maintain my position from the start - to have credibility, you have to be honest about how wildly disruptive and potentially dangerous reactor failures of the Fukushima type can be.
Then you can talk about future reactors with passive safety as their key priority and have some vague hope about people believing you.
And again - yes, there have been some wildly exaggerated claims of danger from Fukushima which are without basis (for example, that there is any danger at all to the US West Coast.) But it's no use pretending that it's not a serious environmental issue in the area around Fukushima.
UPDATE: speaking of bad reporting, I note that the Australian (and the ABC) is saying:
Abnormally high levels of radioactive substances were later detected in seawater 100m from the troubled plant.Yet the AFP report says:
Come on, who's right? (I hope, and would guess, it's the 100 m version.)Tokyo Electric Power Co. (TEPCO) said the level of iodine-131 was 126.7 times higher and caesium-134 was 24.8 times higher than government-set standards.
The substances were detected in seawater which was sampled Monday about 100 kilometres (60 miles) south of the Fukushima No.1 plant, a TEPCO official said.

Most of the danger is not from radiation levels it is from leaked radioactive substances. The chart does not put Fukushima in context.
