RE: Potassium cell study



Philippe,

Thanks for the information, but I am really interested in the potassium cell

study legend.  It is so often quoted, but lacks substance.

John,



John,



Not on K-deprivation experiments, but still on the effects of

deprivation of radiation:



Do a search on "Planel H" on MEDLINE.  This will bring you 84 references

on the effects of lack of radiation on simple organisms (cells and

parameciaes) and mice.  Most demonstrate a detriment in organisms

exposed at levels below background and optimum benefits at 4 - 10 times

background dose rates, that is, close to annual limits for radiation

workers.  



Recent work (Courtade-Saidi M., PhD thesis : Les effets d'une

irradiation gamma chronique à très faible dose sur la souris - Effects

of very low dose chronic gamma irradiation in mice - , Univ. of

Toulouse, France, 2001) shows a reduced risk of cancer and

cardiovascular diseases in exposed mice, at 11.5 cGy/y (35 times

background vs 0.35 cG/y for controls).  



I can e-mail you the "Planel" list I got from MEDLINE if you want to

know.

Ah, yes.  The grand conspiracy.  I knew Charlie, and had a lot of

respect

for him.  However, this is still hearsay evidence.  What I am asking is,

is

there any documentation of such an experiment?  This is the same as

saying

there is a carburetor that allows a car to get 75 miles to a gallon of

gas

(4 liters to our international readers)  Says who? There is a story that

years ago the Navy located all the members of the original Nautilus

crew,

because another story was going around that they had all died from

radiation.  (Story of a story?)  It seems to me that the government

would

have published this report since in the 1950's and 1960's was

encouraging

the use of nuclear power.  



Again, where is the proof of the potassium cell study?



By the way, I could not find the subcommittee report at the NRC Web

Site.  I

tried using the ADAMS, but that leaves much to be desired.  Could you

provide me the link so I can read it myself.

In the part you cut out of the quote, personal knowledge of Charlie

Willis,

CHP, NRC senior staff; go to NRC web site, transcript, March 1996, Joint

Subcommittee of ACRS/ACNW. You also cut out the part about "...because

of

the LNT, this data was not published."
