Helium Diffusion in Zircons — Does it show that the earth is young?

This page — which is an extension of an introduction to this topic in the HOMEPAGE FOR "AGE OF THE EARTH" SCIENCE — is one section in a large page of "potential educational resources" for Radiometric Dating.

Humphreys - A Tale of Two Hourglasses to explain the argument

Helium diffusion rates support accelerated nuclear decay by Humphreys, Austin, Baumgardner & Snelling — is available (as a result of RATE) in HTML and PDF.

Russ Humphreys vs Joe Meert (with introduction by Sarfati)
responding to a critique of RATE by Meert

Do zircons retain too much helium for an old earth?  AiC  TO

Christman - critique of RATE's Zircon-Helium Diffusion Project

Neyman - review of Chapter 4 in RATE-book (Thousands not Billions)

Neyman - re: Humphreys-Henke series (below) and YE persuasion-methods

Here is a series of related papers, about helium diffusion in zircons, by Russell Humphreys and Brad Henke:
1 - Humphreys (by himself or with colleagues) wrote a number of papers, including these:
1a. Humphreys, * Nuclear Decay: Evidence for a Young World (RATE) - 2002
1b. Humphreys, New RATE Data Support a Young World - 2003
1c. Humphreys & others, * Helium Diffusion Age of 6,000 Years Supports Accelerated Nuclear Decay - 2004
2 - Henke [original] - Young-Earth Creationist Helium Diffusion Dates [re: #1] — March 2005
    [and he suggests reading his own revised version in #4]
3 - Humphreys, Helium Evidence… Remains Crystal-Clear * [re: #2 by Henke] — April 2005
4 - Henke [revised] - re: #3 by Humphreys plus Appendices A & B — November 2005
5 - Humphreys, Helium Evidence… Overcomes Pressure [re: #4 by Henke] — January 2006
6 - Henke [re: #5 by Humphreys: Appendices C & D] — July 2006
