Tom Thorne/Beth Williams Wildlife Research Center at Sybille
2362 Highway 34
Wheatland, Wyoming 82201
(307) 322-2571
This facility is closed to the public. It was named in honor of Dr. Elizabeth Williams (prominant CWD expert) and her husband Tom Thorne, Director of Fish and Wildlife in Wyoming. Both were killed in a winter car accident, near Xmas 2004.
Sorry Terry, but there is a connection between this hot zone of CWD and radiation. It has been known about since the early 1970s.

5. Predicted population effects on free-ranging elk based on captive elk chronically exposed to the CWD prion.
Forty-three female elk calves were trapped at the National Elk Refuge and transported to Sybille in February 2002. Elk were housed in pens, assumed to be environmentally contaminated with the CWD prion. Elk will be held throughout their lifetimes. Elk dying will be examined and cause of death determined. From these data, it will should be possible to model free-ranging elk mortality and population dynamics under extreme circumstances of CWD prion exposure and transmission. As of December 2005 (46 months post capture), 11 of 43 elk have died due to CWD. This compares to 100% mortality in less than 25 months in elk orally inoculated with different dosages of the CWD prion.
This is all very interesting since the animals were probably exposed to environments contaminated with radio-active material, as mentioned in Mark Purdey's document quoted above. Fort Collins has been doing research on ionizing radiation and its damaging effects to DNA. Two of Elizabeth Williams last papers (published post humously) were on this very subject (ionizing radiation).
Experimental animals at Fort Collins, I believe that cattle were being referred to, have been fed CWD prions for the last eight and a half years (8.5 yrs) according to Dr. Michael Miller, of Fort Collins (statement made at the Feb 2/06 Prion Symposium which my hubby attended). None of these animals have developed the disease. They have continued to increase the amounts being fed to them, and still no disease. Dr. Danny Matthews, of the VLA in UK, was livid that they were continuing to feed these animals for such a long period. Matthews stated, "kill them at 3 years, and get on with it".
Dr. M. Miller also mentioned that cattle have been living in CWD exposed pens for years and they are all doing fine.
Another example of this is the following study where Dr. Daniel Gould worked with Miller, et al. on histological survey of cattle living in the hot zone of CWD:

(Note: the animals were at least 4 years of age. Since most cattle haven't shown visible symptoms of BSE until they are 6 years of age.)
Another interesting research paper by Dr. DH. Gould, was done in 1998, entitled "Polioencephalomalacia" it is free on line. Search thru "Entrez Pubmed".
Quote:
Within this paper, Gould mentions that respiration of hydrogen sulfide could "serve as a primary entry route" of sulfides into animals. "Cattle exposed to atmospheric manure gas (H2S) developed PEM (Dahme et al, 1983)"
He also noted, under "Studies of Experimental PEM in Colorado", that "PEM was stimulated by the occurrence of PEM in association with copper deficiency and high-sulfate waters in our region. During the course of the experiments on diet-induced copper deficiency in cattle, we observed that copper-deficient experimental diet with added sulfate consistently induced PEM in cattle."
The links are working for me now, Terry. I hope that you will allow me this repeat of my earlier posting. I am not so certain that you read it.
For someone who gets so upset about the issue, I don't know why you think your plutonium comments are funny. Let people read what Purdey wrote regarding CWD at Fort Collins, and how they (Fort Collins) have been, and continue to, monitor the effects of radiation on the animals inhabiting these contaminated lands.
