[ RadSafe ] LAT Article: Ref to "denatured-potassium" studies

Friends,

These refs show the biological effects of potassium from which the K-40 has been removed (in an otherwise low-background condition - external radiation can cover for the loss of K-40 radiation).  Note that the 1950s-'60s Oak Ridge work wasn't published, as Charlie Willis also stated at a joint ACRS/ACNW meeting in March 1996; and I heard from a senior AEC Biology and Medicine research official and senior Oak Ridge official following a meeting on low level radiation health effects in 1972 (I worked for a recently-retired AEC official and we were addressing developing industry policies following the Appeals Court "Calvert Cliffs decision" effects of normal operation radiation releases and Appendix I and Appendix D rulemakings).

See, e.g., Don Luckey’s 1986 paper/abstract at:
http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?db=pubmed&cmd=Retrieve&dopt=Abstract&list_uids=3097750

See some data from Luckey’s paper at:
http://radscihealth.org/RSH/Data_Docs/1-3/2/1321lu86.html 

See also an Alexander Kuzin paper at:
http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?db=pubmed&cmd=Retrieve&dopt=Abstract&list_uids=8148982 

I have seen the abstract of one Russian paper that did similar work, but did not see an effect.  I did not get a response to an inquiry about its significance before Kuzin passed away in '91.

Regards, Jim

Amen John,

Not only would you die without potassium, it is fairly well homeostatically controlled.  

We even know that with just K-39, removing the K-40, and shielding from external radiation, cells and organisms cease to function.

Jerry et al

K-40 is one of the isotopes always seen in whole body counting, and I used 
it to insure may counter was working properly. If the peack at 1.46 MeV was 
not present, the counter was assumed to be not working correctly.
