Carbon dating half life period
In order to take back our site, we have taken the step of removing all the scripts on our site.
That led me to this non-technical article, and from there followed a link to the asa3article. This article does a good job at explaining the technical complexities of measuring the very small amounts of C14 present in these ancient samples and why non-zero amounts are measured.
C14 has a half life of 5730 years and is only good to date objects to 50,000 years or so.
Although I can find any number of references to this seemingly vital finding on the creationist sites, I can find almost no attempt to refute or explain this anomaly on serious science sites. There seem to be some unsubstantiated references to the possibility of neutrons generated by uranium decay resulting in an anomalously high presence of C14.
I still feel that some definitive experiments in this area would be useful to test the various rational explanations for the c14 anomaly. Even so, it is always good when creationists have been casting doubt in some area to be able to completely explode their reasoning.
I can see though that science has problems taking on creationists because of the perceived risk of lending credibility to their ideas. Also as soon as one creationist idea is exploded, they just move on to another area where uncertainty in the science offers them the opportunity to mislead. Several of the test results touted by creationists were definitive experiments to assess those limitations. I'm still looking for a reference, in a refereed scientific journal, confirming the finding of carbon14, in any amount, in diamonds or coal.
