Here’s a powerpoint presentation from an excellent presentation given by Kirk Sorensen about the use of thorium as a nuclear energy resource.
Of course, the Powerpoint slides themselves are not as good as the whole presentation, and in and of themselves they can be a little hard to follow, without the presenter, but unfortunately you have to deal with that with any presentation where you’ve only had a chance to pick up the slides after the fact.
This presentation was prepared over a year ago – but I was only reading it last week. As for the title of this post – there was something, on a related note, that I found a little amusing.
Check out the 6th slide, in Kirk Sorensen’s presentation, and compare it to the oh-so-factual and educational graphics used in Joseph Romm’s recent post on GristMill. Isn’t it uncanny – just when you thought that nobody trying to construct a coherent (?) argument of some kind against the use of nuclear energy could actually be that silly.
Joe Romm has got another post up recently that’s worth looking at as well, in which he attempts to reinforce the notion that the linear-non-threshold hypothesis is somehow factually motivated, and that every little contribution to low doses of ionising radiation is dangerous. I’m sure some readers will be interested in going and leaving a comment in response to that.
Still, Romm deserves some credit for correctly pointing out that on the grounds of ionising radiation dose, as well as numerous other ecological and health impacts, coal-fired electricity generators are far more dangerous than nuclear power plants.
Also, in one final note, congratulations to Rod Adams on the momumental 100th episode of The Atomic Show podcast. That’s a monumental effort, producing 100 episodes of interesting, unique high-quality podcasting, interviews and commentary, and I look forward to the next 100 episodes to come.
A beautiful analogy to explain why the LNT hypothesis seems like it might be something of a stretch:

If the LNT were applied to falling as it is to radiation, we might note that 100 percent of those falling onto concrete from 100 feet are killed, but only 50 percent of those falling from 50 feet die. With these data we would linearly extrapolate to say that 10 percent falling from 10 feet and one percent of those falling from one foot would die. Armed with this “linear no-threshold falling theory,” we could confidently assert that jumping rope should be banned on all school playgrounds since statistically anyone making 100 one-foot jumps would die.
