Jim,
    Several years ago, Don Luckey tried to obtain research funding  to
determine the effects of raising animals on K-40 free diets (i.e. all
potassium consumed bring K-139).  As I recall, he did not receive support
from DoE or any other agency for the purpose. What's the evidence showing
indicating adverse effects from K-40 deficiency?

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.

Regards, Jim

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.
