Although I like the gist of your comment I have a nitpick:
The risk of being injured by a nuclear meltdown today is on par with being injured by lightning.
Your risk of injury from nuclear meltdown is orders of magnitude less than getting hit by lightning. Think about it, people get hit by lightning all the time in comparison the number of nuclear meltdowns in the nation. And no one was "injured" at our last nuclear meltdown (Three Mile Island) so even given an incredibly rare meltdown you have a incredibly minute chance of injury unless you happened to be working in the containment building.
Now, Three Mile Island did release radioactive contamination to the atmosphere, but the affect on the surrounding population was slight. Of course, not everyone agrees. I can't speak to the findings of the various researchers but I can say that several of Mr. Wasserman's claims are either misleading or flat-out wrong:
The public was told there was no danger of an explosion. But there was, as there had been at Michigan's Fermi reactor in 1966. In 1986, Chernobyl Unit Four did explode.
Even the Chernobyl explosion was non-nuclear, caused by the water in the coolant tubes being instantly converted to steam during the accident and literally blowing the lid off of Chernobyl. A hydrogen bubble was present in the reactor core after the meltdown but could not have exploded without the presence of oxygen to combust with, but oxygen is kept out of the coolant due to corrosion concerns.
there is no safe dose of radiation, and none will ever be found.
Well there is no set level under which you can say that a person will be just fine, but at the same time each and every single one of us live in a field of ionizing radiation from natural/cosmic sources all the time. Life has been adapted to low-level ionizing radiation due to this. If it were not the case then therapies such as medical radioimaging would not be performed, not to mention procedures like X-raying. For the same reason, people are allowed to fly on airplanes even though the radiation you receive in flight is much higher than on the ground due to less atmospheric shielding while in flight. Mr. Wasserman is correct that radiation damage is more harmful to fetuses, unborn babies, and children due to the reduced amount of time available to repair the damage before cell division. However we let pregnant women fly so apparently there must be some level of ionizing radiation that we believe unborn children can withstand.
Much of the rest of his assertions is a they-said/I-said where he discounts studies and government reports that disprove his claim by invoking the ever-popular conspiracy theory and then he submits his claims based on experts who agree with his claim. I can say people in Harrisburg didn't suffer symptoms, as I've certainly never walked door to door there. I can say that the trial court in Pennsylvania where the TMI cases were adjudicated ended up throwing out the lawsuits due to lack of evidence.
In addition Mr. Wasserman talks about "anecdotal" evidence of "Many [central Pennsylvanians] quickly developed large, visible tumors, breathing problems, and a metallic taste in their mouths that matched that experienced by some of the men who dropped the bomb on Hiroshima." This is nice and all except that the metallic taste is due to gamma radiation, which was produced in copious amounts during the Hiroshima bombing, but not so much in the radioactive release from TMI (otherwise there would have been more than "anecdotal" evidence for its existence). I'm not sure if Mr. Wasserman was leading the questions or simply allowing peoples fears to guide what they thought they were feeling but this kind of effect is very far-fetched.
Speaking of fear, Mr. Wasserman seriously mentions "a harrowing broadcast from ... Walter Cronkite" as evidence that something bad happened. Well, something bad did happen, but that doesn't speak to whether people received serious injury or not. I could go on but this article has apparently been debunked better already.
Anyways, back to my main point. I'd be more worried about getting struck by lightning 3 or more times than by suffering injury due to nuclear meltdown here in the USA.
