Radiometric dating and the age of the earth
http://creation.com/images/pdfs/cabook/chapter4.pdf Carbon-14 in coal suggests ages of thousands of years and clearly contradict ages of millions of years.
http://globalflood.org/papers/2003ICCc14.html Carbon-14 in oil again suggests ages of thousands, not millions, of years.
http://creation.com/radioactive-dating-in-conflict Carbon-14 in fossil wood also indicates ages of thousands, not millions, of years.
http://creation.com/diamonds-a-creationists-best-friendhttp://creation.com/diamonds-a-creationists-best-friend#objections Carbon-14 in diamonds suggests ages of thousands, not billions, of years. Note that attempts to explain away carbon-14 in diamonds, coal, etc., such as by neutrons from uranium decay converting nitrogen to C-14 do not work. See: Objections.

http://creation.com/images/pdfs/cabook/chapter4.pdf Incongruent radioisotope dates using different techniques argue against trusting the dating methods that give millions of years (or billions of years for the age of the earth).
http://creation.com/contra-rb-sr-datinghttp://creation.com/the-failure-of-u-th-pb-dating-at-koongarra-australia Demonstrably non-radiogenic 'isochrons' of radioactive and non-radioactive elements undermine the assumptions behind isochron 'dating' that gives billions of years. 'False' isochrons are common.
Different faces of the same zircon crystal and different zircons from the same rock giving different 'ages' undermine all 'dates' obtained from zircons.
http://creation.com/radiometric-dating-breakthroughs Evidence of a period of rapid radioactive decay in the recent past (lead and helium concentrations and diffusion rates in zircons) point to a young earth explanation.
The amount of helium, a product of alpha-decay of radioactive elements, retained in zircons in granite is consistent with an age of 6,000±2000 years, not the supposed billions of years. See: Humphreys, D.R., Young helium diffusion age of zircons supports accelerated nuclear decay, in Vardiman, Snelling, and Chaffin (eds.), Radioisotopes and the Age of the Earth: Results of a Young Earth Creationist Research Initiative, Institute for Creation Research and Creation Research Society, 848 pp., 2005
Lead in zircons from deep drill cores vs. shallow ones. They are similar, but there should be less in the deep ones due to the higher heat causing higher diffusion rates over the usual long ages supposed. If the ages are thousands of years, there would not be expected to be much difference, which is the case (Gentry, R., et al., Differential lead retention in zircons: Implications for nuclear waste containment, Science 216(4543):296–298, 1982; DOI: 10.1126/science.216.4543.296).
http://creation.com/radiohalos-startling-evidence-of-catastrophic-geologic-processes-on-a-young-earth Pleochroic halos produced in granite by concentrated specks of short half-life elements such as polonium suggest a period of rapid nuclear decay of the long half-life parent isotopes during the formation of the rocks and rapid formation of the rocks, both of which speak against the usual ideas of geological deep time and a vast age of the earth. See, Radiohalos: Startling evidence of catastrophic geologic processes, Creation 28(2):46–50, 2006.
http://creation.com/the-collapse-of-geologic-time Squashed pleochroic halos (radiohalos) formed from decay of polonium, a very short half-life element, in coalified wood from several geological eras suggest rapid formation of all the layers about the same time, in the same process, consistent with the biblical 'young' earth model rather than the millions of years claimed for these events.
http://creation.com/australias-burning-mountain Australia's 'Burning Mountain' speaks against radiometric dating and the millions of years belief system (according to radiometric dating of the lava intrusion that set the coal alight, the coal in the burning mountain has been burning for ~40 million years, but clearly this is not feasible).
