Humphreys has not silenced his critics, we are waiting for him to answer our numerous questions. Talkorigins permanently archived the original version of this essay after the first update on November 24, contrary to erroneous statements in footnote 25 of Humphreys b. I further revised my essay on November 24, to reply to Humphreys a and again on July 25, in response to Humphreys In the current June, , version, I extensively updated and reorganized the essay to: 1 include materials from other critics of Dr.

Synopsis by Greg Neyman. First Added 4 May Kevin Henke of the University of Kentucky has published a page analysis of young earth creation science attacks upon helium evidences related to the dating of the earth. This article can be found here opens a new window, off-site. Russell Humphreys has responded to this article, with a 13 page answer , which seeks to explain the faulty work of Dr. Henke's review. However, as the information on the right of Henke's article suggests, Humphreys response raises more issues and does not answer the mail.



Dr. Humphreys' Young-Earth Helium Diffusion "Dates"
Scientists use certain elements present in a certain abundance to calculate an approximate age for rocks. One of the decay ratios used is Uranium decaying through a series of alpha and beta decays to Lead. The number in superscript preceding the element name indicates the atomic mass, the sum of its protons and neutrons. Alpha decay releases a Helium nucleus two protons and two neutrons from the parent atom to create two atoms: the released Helium and a daughter product that has an atomic number two less than the original and an atomic mass four less than the original. Using the amount of the remaining Uranium, the amount of Lead that has built up, and the original amount of Lead which is not created by any known decay process, scientists can calculate an approximate age based on the decay rate of Uranium and the ratios of Uranium to Lead and Lead to Lead.





Helium dating , method of age determination that depends on the production of helium during the decay of the radioactive isotopes uranium , uranium , and thorium Because of this decay, the helium content of any mineral or rock capable of retaining helium will increase during the lifetime of that mineral or rock, and the ratio of helium to its radioactive progenitors then becomes a measure of geologic time. If the parent isotopes are measured, the helium dating method is referred to as uranium—thorium—helium dating; if only the alpha-particle emission and helium content are measured, the method is called the alpha-helium radioactive clock.
