How do YECs explain why there are no short-lived radioisotopes found in nature?

Depth of sample      temperature    measured/theoretical
  (meters)                  (C)            helium

  surface                     20              1
  960                        105             .58
  2170                       151             .27
  2900                       197             .17
  3501                       239             .012

"measured/theoretical" means how much helium is present divided by how much has diffused out.Would you please apply the "1D diffusion calcs graphed in the RATE book" to explain how these data show a "100,000 fold excess" of helium???Do you remember a brief exchange we had recently about closure temperature?????This is the third or fourth time you have trotted out this bald assertion as if it were supported by evidence, only to waffle and delay when asked to produce the data.

...I think it is the argon in the air that is most dangerous(???) Guess where it comes from? Radioactive decay of heavy elements. It would have taken time for the argon to diffuse out of the rocks.

BINGO! We have a winner! Argon diffuses more slowly than helium. So there should be more helium in the atmosphere relative to argon (if the Earth is so young as TB believes), yet the ACTUAL DATA show that argon is enriched by a factor of 6564 times in the atmosphere (vs helium). How could all that argon have diffused out in only a few thousand years???Answer... it took billions of years, during which time the helium escaped from the atmosphere, leaving the argon behind.

Anybody - feel free to correct me on this paragraph.

OK...
argon is NOT radioactive,
so it is NOT the "most dangerous",
it is NOT produced by decay of heavy elements,
helium is NOT found in "excess" in granites,
"Po halos" are NOT formed instantly,
argon diffuses far too slowly to account for the observed abundances in the atmosphere for the YEC myth to be accurate......and there's plenty more corrections needed in many, many more posts. Unfortunately, TB, you post unfounded and unsupported fantasies faster than any ten scientists can demonstrate how wrong you are in almost all areas relating to geology. And then, even when shown the actual data, you just ignore it and repeat the fantasies all over again. How many times have you repeated the "100,000 fold" story? A search of this forum turned at least 8 posts making this claim. None cited any data, just the ICR appeal for donations and vague references to the RATE book. Each time, you were asked by edge, JM or myself - sometimes more than once - to produce actual data, samples... anything of substance. Sometimes you offered to fetch these data and calculations, but nothing has been produced.
Explanation?

Have you read the relevant chapter from the RATE book? [/QUOTE][/b]
No, I don't HAVE the book. YOU do. Please provide the data FROM the book. Please post it HERE. THANK you.

I intend to raise the closure temperatue with Snelling et al. At this point I stand by the RATE book but I do not belittle your point and will refer to your posts with a link and comment from now on.

Thank you. But why not a link to actual data in THIS post. Are we waiting for Godot? [QUOTE][b]You can't simply look at argon/helium ratios. What about the respective amounts of parent nuclei? [/QUOTE][/b]
That's exactly what I am trying to point out to you. The ratio of the parent nuclei is .27 Ar-producing K for every He-producing step in the U/Th decay series.In the atmosphere, there are 1772 40Ar for every 4He. [QUOTE][b]I wont concede that helium is NOT found in "excess" in granites.[/QUOTE][/b]
Then show me some data where it IS found "in excess". I have already shown data where He is depleted or entirely absent. For diffusion to be responsible, millions of years are required. Plug the data above into your diffusion equations from the RATE book.

I never said that "Po halos" are formed instantly. I see halos as evidence of decay as you do.

My mistake. "Instant" Po-halos are a staple of the Creationist mythology/fundraising points.

I have not seen an equilibrium budget on Argon so no comment on that.

I do not see how it could be at equlibrium, since it is being added but not removed from the atmosphere and earth.
