The challenge in C content of groundwater at the time of recharge, i.e., at the time when groundwater is isolated from exchange with the soil air and moves away from the water table.
There is also a stable isotope of carbon, C is calibrated against an NBS (National Bureau of Standards) oxalic acid standard.
Let's say I have a bunch of, let's say these are all atoms. And let's say we're talking about the type of decay where an atom turns into another atom. Or maybe positron emission turning protons into neutrons. And we've talked about moles and, you know, one gram of carbon-12-- I'm sorry, 12 grams-- 12 grams of carbon-12 has one mole of carbon-12 in it.
So you might get a question like, I start with, oh I don't know, let's say I start with 80 grams of something with, let's just call it x, and it has a half-life of two years.
The Bible, by contrast, paints a radically different picture of our planet's history.The water leaking out the sides of the barrel represents the loss (mainly by radioactive decay) of the atmosphere's supply of carbon-14.Evolutionists generally feel secure even in the face of compelling creationist arguments today because of their utter confidence in the geological time scale.Amateur Radio | |Biology | Books | Chemistry | Data Sheets | Electronics | Math | Microscope | NASA-TV | | Photography | Physics | Radio Astronomy | Robots | Science News | Space-Astronomy | Transistors | Search This Site | The OCR Carbon Dating Home Page Carbon Dating Carbon Dating How accurate are Carbon-14 and other radioactive dating methods?

Howstuffworks "How Carbon-14 Dating Works" radiocarbon WEB-info The method How accurate are Carbon-14 and other radioactive dating methods? At an archaeological dig, a piece of wooden tool is unearthed and the archaeologist finds it to be 5,000 years old.A child mummy is found high in the Andes and the archaeologist says the child lived more than 2,000 years ago.Carbon 14 is used for this example:, which was put out by Dr. is presently only 1/3 of the way to an equilibrium value which will be reached in 30,000 years. Knowing how faulty creationist "facts" can be, let's do a little research of our own.This nullifies the carbon-14 method as well as demonstrating that the earth is less than 10,000 years old. One suspects that the scientific world would not be using the carbon-14 method if it were so obviously flawed.The water coming out of the hose is analogous to the continuous production of carbon-14 atoms in the upper atmosphere.The barrel represents the earth's atmosphere in which the carbon-14 accumulates. It was discovered in 1934 by Grosse as an unknown activity in the mineral endialyte. This half life has later been re-determined by Godwin. Libby recognized that due to its occurrence in natural materials, either by simple mixing processes or by carbon exchange.In the same year, Kurie (Yale) exposed nitrogen to fast neutrons and observed long tracks in a bubble chamber. The mean life time of roughly 8000 years is ideal for dating of reservoirs that are a few decades to a few ten thousand yeas old.The internationally accepted radiocarbon dating reference is 95% of the activity, in 1950 AD, of the NBS oxalic acid normalized to C activity: » 50 pmc Chemical and isotopc evolution in recharge zone: (Fig) (Fig) Open and closed system conditions ‘real world’ systems are somewhere in between open and closed and the correction models mentioned above and described in Clark and Fritz (chapter 8) have to be applied.
