Re: [Phys-l] Isotope chemistry and physics

In BC's original reply there was a link below the D2O statement (see Bill's note below):
http://www.isb.vt.edu/brarg/brasym96/kushner96.htm

In that paper there is the statement:
**

Since this conference is largely concerned with the risks of releasing different substances into the environment, it should be stated at the beginning that D2O itself poses little such risk--so long as it has not been used in nuclear reactors. As will be seen below, D2O itself is not toxic to animals, except under exceptional and very improbable circumstances.
**

This matches my understanding and I'm assuming Bill Nettles' understanding. The paper does go on to note that in nuclear reactors the D changes to T which is radioactive and is thus a clear risk.

As far as I know, the biggest risk in drinking D2O is to your pocketbook.

All the best,

John

D20 is poisonous? I'm interested in why you say this.

On a much grosser scale is the concentration of, for a notorious
example, mercury up the food chain. Another isotopic example:
Because the difference is so great, D2O is poisonous!!! [snip]
