This is true. However, new C-14 is being continuously produced in the high atmosphere.CArbon is beinbg lost by the biological process of changing 14C to 14N, so there is less carbon than at creation. As I understand it carbon-14 is cahnged to nitrogen-14 by a 40 day process.
No this is incorrect the carbon decays back into Nitrogen.Jbuza wrote:I find this half- life interesting because it corresponds very closely with the age of the earth. Also when I was reading the page and as I understand carbon-14 production, that there is less and less available carbon on this planet as time goes by.above link wrote:An example of a beta-emitter is carbon-14. Carbon-14 is a naturally occurring radioisotope found in the Earth's atmosphere. It can also be manufactured by humans. It has a half-life of 5,700 years. The natural amounts of Carbon-14 that have been taken into organic materials are often used in archaeological studies to determine the ages of human remains and other organic artefacts from ancient civilisations.
Not sure what you're trying to say here, since the carbon 14 half life is 5,700 years accurate measurements can only go back 50,000 years. (Even farther with more modern measurement techniques.)Jbuza wrote:This should be of interest to carbon based life.
If accurate carbon-14 measurments can be taken, this establishes a carbon loss rate, that can be extrapolated 4.5 billion years into hypothetical geological time.
Again not sure what you mean here. Carbon 14 decays into Nitrogen.Jbuza wrote:Nope won't work because carbon 14 daughters to Carbon-12 which is its parent, but nontheless I find carbon-14 half life to be interesting.
You forget that the C14 came from Nitrogen in the first place.Jbuza wrote:CArbon is beinbg lost by the biological process of changing 14C to 14N, so there is less carbon than at creation.
Incorrect carbon 14 has a half life of 5730 years. And this decay is not a biological process.Jbuza wrote:As I understand it carbon-14 is cahnged to nitrogen-14 by a 40 day process.
They do occur but only in trace ammounts and this quantity can be attributed to the decay of other particles such as Uranium 238.Jbuza wrote:I had asked earlier what your evidence that Uranium 236 and Technetium-99 do not occur naturally on earth, but never got an answer?BGoodForGoodSake wrote:This doesn't have anything to do with what I posted.Jbuza wrote:Chapter 5 of Dr. Fange book presents numerous findings that show geological time and thus evolution to be the drivel it is.

Please just let me know if you accept the following as facts or not.
Uranium-236 has a half-life of 23.9 million years
Technetium-99 has a half-life of 0.212 million years (thats 212,000 years.)
They don't occur naturally on earth.
Plutonium-244 has a half-life of 80 million years and can only be found in very trace quantities as a result of a rare process in uranium-238 decay.
No it's a commercial byproduct of nuclear reactors used in medicine.Jbuza wrote:Also then are you saying they are here by some supernatural cause?
The abundance of elements on earth follows a pattern with elements lower on the periodic table being more than those higher, yet these lements are far less abundant than would be predicted by this curve.Jbuza wrote:Also If you could deal with those issues and I was really hoping that you were going to take this explanation of radiometric dating further.
14N is converted in the upper atmosphere into 14C. The 14C then decays at a constant rate back to 14N. These are nuclear reactions and essentially independent of the chemical or biological environment.Jbuza wrote: So Nitrogen is converted into 14C and 14C is converted to 12C by radiation and to N by biological processes.
http://science.howstuffworks.com/carbon-142.htm wrote: When the neutron collides, a nitrogen-14 (seven protons, seven neutrons) atom turns into a carbon-14 atom (six protons, eight neutrons) and a hydrogen atom (one proton, zero neutrons). Carbon-14 is radioactive, with a half-life of about 5,700 years.
YOU ASKED ME IF IT WAS A SUPERNATURAL CAUSE!Jbuza wrote:How is this not a natural cause? AGain either it is here by a natural cause or you are saying that humans are supernaturalBGoodForGoodSake wrote:No it's a commercial byproduct of nuclear reactors used in medicine.
Again this is not a jab at you, I remeber asking earlier.Jbuza wrote:Also then are you saying they are here by some supernatural cause?
Natural cause and occuring naturally are not the same thing.Jbuza wrote: Well they are either akin to biological processes, or else man is supernatural. If you want to be able to complain about the actions of man like global warming and such, than you must believe that his actions are not part of the natural order. Either man is a product of natural selection and is simply a higher animal in which case there is no ground to complain about what he does any more than what another animal does, or else man is separate from the animals and his actions are more than biological processes. I don't see how you can have it both ways. So is the presence of the elements here by natural processes or not?
