Mr. Carnes, name one person who quoted that text. After naming that person, prove that they simply accepted it on faith. (Maybe my machine misses some news articles, but I never saw that quote used by anyone.) >Now let us see how Paul and Anne Ehrlich review his contribution to >*The Resourceful Earth*, an article on "The Hazards of Nuclear >Power": First let us take a closer look at Dr. Cohen. He recieved his doctoral degree from the Carnegie Institute of Technology in 1950, worked for eight years at Oak Ridge National Labs where he was in charge of cyclotron research and is now professor of physics at the University of Pittsburgh. He was also past chairman of the American Physical Society, division of nuclear physics. Dr. Cohen has written numerous papers in the area of nuclear physics. I have already gone over the "unique qualifications" of Mr. Ehrlich in a different article and it is distasteful enough that I don't want to go into it again. > ...If Cohen had accurately represented his references on this point, > his conclusion would have been that the health risks from routine > operation of nuclear power, measured as loss of life expectancy in > the present generation, may well exceed the corresponding risks from > coal-produced air pollution. Fortunately you of course only left the conclusion here so it is impossible to directly prove or disprove Mr. Ehrlich's statements. But let us examine some of the more important research on the topic. The most authoritative report on coal usage that I know of, is "The Direct Use of Coal" written by the OTA of the U.S. government. (I believe that this work also includes the latest research from Brookhaven Naval Labs.) The calculations used for this report are quite meticulous and, for example, included correlations for every square kilometer of the U.S. Based on their research, this report estimated 48000 deaths from coal burning during the year 1975. (With higher coal burning now higher, the deaths of course are of course higher.) If you want to argue that the people killed by coal emissions are mainly older people or those with lung problems, and thus society isn't hurt as much by those people dieing, then please be explicit about your position. Considering other obvious long term disadvantages of coal, such as the possible links to acid rain, the environmental disadvantages from strip mining, the numerous deaths from coal mining, the almost impossible problem of coal waste disposal, and the deaths from transporting coal it is obvious we pay a serious price for coal. I have yet to see any statements that nuclear power has more serious health risks. > Cohen's treatment of the longer-range hazards of coal and nuclear > energy is of even lower quality.

As far as uranium mining reducing long run cancers, there is growing evidence for this view. One way of comparing toxic potential is to compute the volume of water in which the toxin must be diluted to bring it down to internationally accepted maximum permissible standards in drinking water. In this way you can compare the toxic potential of all toxins, whether they be radioactive, biological or chemical. K.D.B. Johnson, a British scientist at the United Kingdom Atomic Energy Authority calculated the toxic potential of a number of naturally occurring substances in this way. What he found was suprising, after appox 500 years nuclear wastes are less toxic then coal wastes and after about 5000 years are less toxic then the uranium ore they came from. A more obvious approach is to simply realize that uranium is poisonous and radioactive and will by itself get into the natural environment and water supply. By mining it, we are eliminating this chance and are preventing those deaths. The amount of lives saved probably isn't large. (I shall have to find Cohen's paper on that, it does sound interesting) What is far more important are the hundreds of lives saved every time a coal plant *isn't* put on line. > On the basis of the "estimates" Cohen reaches this ringing > conclusion: "Every time a coal-burning plant is built instead of a > nuclear plant, many hundreds of people are condemned to premature > death." The best research indicates that coal causes 48,000 premature deaths. If coal causes 48,000 premature deaths and nuclear power doesn't, then obviously every time a coal-burning plant is built instead of a nuclear plant, many hundreds of people are condemned to premature death. While Ehrlich may want to avoid this conclusion, I would hope that policy makers don't. >Cohen replied with an indignant letter to the *Bulletin* (Sept. >1985). The Ehrlichs responded: > > The opinion poll of which Cohen is so proud was intended to show that > the media have exaggerated the hazards of radiation, thereby > contributing to a degree of public opposition to nuclear power that > Cohen considers irrational.

Again we have the old technique that anyone associated with that great evil of radiation can not be trusted. Frankly I am pretty damn sick of this sort of baiting - as I said before, first show the reader why this entire field is lacking in scientific integrity. As I have shown before, there is hardly even a conflict of interest. As people have said, it is the simplistic thinking of some of the anti-nuke people that is worrisome. > As for the hazards of trace metals released in coal burning, Cohen's > reference on this point in his chapter was an unpublished manuscript > by himself.

[Paul and Anne Ehrlich] The fact that Ehrlich missed two articles in the scientific journals does not surpise me, at least. The fact that he then off-handlely dismisses the original research and the journal's internal review staff as incompetent, is not very surprising either considering the quality of the rest of Ehrlich's writing. Do I need to go on? If you want to question the integrity of a reputable scientist, let's see references to articles in the scientific non-ideologial journals. Now, the major reference to Dr. Cohen on the net has been his work in plutonium toxicity. This research you haven't addressed. Indeed, I believe that your disagreement on toxicity was based on a paper by John Gofman. I will take the case of Gofman up later. -- Michael V.
