Talk:Deuterium-depleted water

Rationale
I have started this page in an attempt to consider the efficacy (or otherwise) of a new chemotherapy adjunct...sealpoint33

A laudable effort. Quite reasonably, few of us will care, but the distinction is correct and ‘pedia-worthy. I appreciate, and praise, the edit, even tho it would not have occurred to me. And it leaves me vaguely curious as to the rate of decay of the concentration of “doubly-labelled” molecules: after all, one ten-millionth is damn small, and I refuse to try to estimate the relaxation time of of heavy water molecules, let alone even think about the ... arrgh ... Differential decay rate of doubly-labeled molecules ... it takes a braver physicist than i to seriously consider the relaxation time of doubly-heavy-water molecules, ya hear me, Gunga Din?

Article expansion
Someone may include a link to Interplanetary_spaceflight, where it is mentioned that water with low deuterium content might be used for extended space travels for radiation protection.

Also check deuteriumdepletion.com and the videos on youtube.

I have a problem with the first sentence. It should say that it is a lower concentration of deuterium than naturally abundance. It doesn't state if it is higher or lower and is therefore misleading. — Preceding unsigned comment added by 204.232.68.202 (talk) 16:42, 4 September 2013 (UTC)

Merge
This is a little messy. Light water has two uses: DDW and plain water (used w/r/t nuclear reactors to distinguish them from heavy water reactors.) Light water used to have a discussion of LWRs and someone cut and pasted the material to LWR without merging the history or talk page. So the first thing that should happen is that the current light water should merge with light water reactor.

After that's over, I propose merging this page into the light water namespace.

That's based on my own knowledge of usage; however, the medical journals seem to prefer DDW. If other users only come across the topic w/r/t its potential use in chemo, perhaps it's better that the topic stay here with a redirect here from light water and a disambig over to LWR.

Structural updates to article
I did some work on this article, which included adding material, sections, and a lead, as well as changing its citation style to the easier to read R|....  to help see issues. If there are still citation issues, please specify here what else needs to be done to keep the citation issues flag off the page. RobP (talk) 03:55, 11 July 2020 (UTC)
 * Thanks for adding content! Regarding change of cite style, I think you violated WP:CITEVAR. I see two cn tags, each on a complex sentence or train of thought. Could you explain what specific parts are of concern in these (links omitted thoughout):
 * "The deuterium atom (whether bonded or ionized) is a heavier isotope of hydrogen, having (in each atom, in addition to its single proton) a neutron that (very nearly) doubles the atomic mass of the atom compared to the vastly more common protium (1H) isotope.[citation needed]"
 * "The production of heavy water involves isolating and removing deuterium containing isotopologue within natural water. The by-product of this process is deuterium-depleted water.[citation needed]"
 * The first is a string of basic definitions and simple numerical comparisons of them. The second is a tag for the statement "If you have [A+B] and you take [A] away, you have [B] left", which seems pretty basic elementary/middle-school math. DMacks (talk) 11:03, 11 July 2020 (UTC)
