Barry Brook (and Co.) on Dr. Caldicott's Latest Claims on Radiation From Nuclear Plants

The debate on the effects of radiation from nuclear plants is alive and kicking at Barry Brook's blog Brave New Climate. In his latest post, he takes on Dr. Caldicott's latest junk piece that surfaced in Online Opinion:
The focal claim from Caldicott in this piece is that it is dangerous to live near to nuclear power plants (NPP), because they supposedly increase rates of leukemia.

My basic response to such a claim is quite simple, and I think useful, because it cuts through the somewhat arcane and context-laden epidemiological arguments. It’s this: The additional radiation exposure of those living in the vicinity of NPP is ~0.0002 millisieverts (mSv), versus a background level of 2 to 4 mSv (depending on where you live) — the latter due to everything from cosmic rays, to ground-derived radon emissions, to eating bananas (this last one gives you more radiation than the NPP). So that’s 1/15,000 of your total yearly dosage coming from the ambient levels produced by nuclear power (in the US). Living near a coal-fired power station would give you 100 to 300 times more radiation exposure, and even that is trivial and not the reason coal burning is damaging to your health.

So, here is an apparently straightforward intellectual challenge. Can proponents of such an argument as Caldicott’s explain how something which adds 0.007% to an existing effect (background radiation) is somehow critically important, when adding 100 to 300% (or more) to an effect by simply moving from a house built on sedimentary rocks to one built atop granite, or moving from the state of New York to Colorado, is irrelevant?
And so the debate took off in the comments. Be sure to stop by because on top of Barry's piece, there is also some valuable info from many of our frequent bloggers (DV82XL, Finrod, David Walters and G.R.L. Cowan).

It's been quite a while since we posted anything on Dr. Caldicott's bogus radiation claims, funny enough I thought she disappeared after she received a mediocre reception in the US when she came out with her latest book. Low and behold, she's still around, but I guess we shouldn't be worried, her claims are in an opinion piece.

A Billion Miles Under Nuclear Energy (Updated)

And the winner is…Cassini-Huygens, in triple overtime.

The spaceship conceived in 1982 and launched fifteen years later, will crash into Saturn on September 15, after a mission of 19 years and 355 days, powered by the audacity and technical prowess of scientists and engineers from 17 different countries, and 72 pounds of plutonium.

The mission was so successful that it was extended three times; it was intended to last only until 2008.

Since April, the ship has been continuing to orbit Saturn, swinging through the 1,500-mile gap between the planet and its rings, an area not previously explored. This is a good maneuver for a spaceship nearing the end of its mission, since colliding with a rock could end things early.

Cassini will dive a little deeper and plunge toward Saturn’s surface, where it will transmit data until it burns up in the planet’s atmosphere. The radio signal will arrive here early Friday morning, Eastern time. A NASA video explains.

In the years since Cassini has launc…

Sneak Peek

There's an invisible force powering and propelling our way of life.
It's all around us. You can't feel it. Smell it. Or taste it.
But it's there all the same. And if you look close enough, you can see all the amazing and wondrous things it does.
It not only powers our cities and towns.
And all the high-tech things we love.
It gives us the power to invent.
To explore.
To discover.
To create advanced technologies.
This invisible force creates jobs out of thin air.
It adds billions to our economy.
It's on even when we're not.
And stays on no matter what Mother Nature throws at it.
This invisible force takes us to the outer reaches of outer space.
And to the very depths of our oceans.
It brings us together. And it makes us better.
And most importantly, it has the power to do all this in our lifetime while barely leaving a trace.
Some people might say it's kind of unbelievable.
They wonder, what is this new power that does all these extraordinary things?

Missing the Point about Pennsylvania’s Nuclear Plants

A group that includes oil and gas companies in Pennsylvania released a study on Monday that argues that twenty years ago, planners underestimated the value of nuclear plants in the electricity market. According to the group, that means the state should now let the plants close.


The question confronting the state now isn’t what the companies that owned the reactors at the time of de-regulation got or didn’t get. It’s not a question of whether they were profitable in the '80s, '90s and '00s. It’s about now. Business works by looking at the present and making projections about the future.

Is losing the nuclear plants what’s best for the state going forward?

Pennsylvania needs clean air. It needs jobs. And it needs protection against over-reliance on a single fuel source.

What the reactors need is recognition of all the value they provide. The electricity market is depressed, and if electricity is treated as a simple commodity, with no regard for its benefit to clean air o…
