Radiocarbon Dating Half Life

While 12 C is the most abundant carbon isotope, there is a close to constant ratio of 12 C to 14 C in the environment, and hence in the molecules, cells, and tissues of living organisms. This constant ratio is maintained until the death of an organism, when 14 C stops being replenished. At this point, the overall amount of 14 C in the organism begins to decay exponentially.

Therefore, by knowing the amount of 14 C in fossil remains, you can determine how long ago an organism died by examining the departure of the observed 12 C to 14 C ratio from the expected ratio for a living organism. Radioactive isotopes, such as 14 C, decay exponentially. The half-life of an isotope is defined as the amount of time it takes for there to be half the initial amount of the radioactive isotope present. We can use our our general model for exponential decay to calculate the amount of carbon at any given time using the equation,.

Returning to our example of carbon, knowing that the half-life of 14 C is years, we can use this to find the constant, k. Thus, we can write:. Simplifying this expression by canceling the N 0 on both sides of the equation gives,. Solving for the unknown, k , we take the natural logarithm of both sides,.

Since the Bible is the inspired Word of God, we should examine the validity of the standard interpretation of 14 C dating by asking several questions:. All radiometric dating methods use scientific procedures in the present to interpret what has happened in the past. The procedures used are not necessarily in question. The interpretation of past events is in question. The secular evolutionary worldview interprets the universe and world to be billions of years old.

The Bible teaches a young universe and earth. Which worldview does science support? Can carbon dating help solve the mystery of which worldview is more accurate? The use of carbon dating is often misunderstood. Carbon is mostly used to date once-living things organic material. It cannot be used directly to date rocks; however, it can potentially be used to put time constraints on some inorganic material such as diamonds diamonds could contain carbon Because of the rapid rate of decay of 14 C, it can only give dates in the thousands-of-year range and not millions.

There are three different naturally occurring varieties isotopes of carbon: Carbon is used for dating because it is unstable radioactive , whereas 12 C and 13 C are stable. Radioactive means that 14 C will decay emit radiation over time and become a different element. If 14 C is constantly decaying, will the earth eventually run out of 14 C? The answer is no. Carbon is constantly being added to the atmosphere. These cosmic rays collide with atoms in the atmosphere and can cause them to come apart.

Neutrons that come from these fragmented atoms collide with 14 N atoms the atmosphere is made mostly of nitrogen and oxygen and convert them into 14 C atoms the neutron is accepted and a proton is ejected from the nucleus. Or maybe positron emission turning protons into neutrons. But that's not what's relevant here. Let's say we have a collection of atoms. And normally when we have any small amount of any element, we really have huge amounts of atoms of that element. And we've talked about moles and, you know, one gram of carbon I'm sorry, 12 grams-- 12 grams of carbon has one mole of carbon in it.

One mole of carbon And what is one mole of carbon? This is a ginormous number. This is more than we can, than my head can really grasp around how large of a number this is. And this is only when we have 12 grams. For example, one kilogram is about two pounds. So this is about, what? I want to say [? And pounds is obviously force. You get the idea. On Earth, well anywhere, mass is invariant. This is not a tremendous amount.

So with that said, let's go back to the question of how do we know if one of these guys are going to decay in some way. And maybe not carbon, maybe we're talking about carbon or something. How do we know that they're going to decay? And the answer is, you don't. They all have some probability of the decaying. At any given moment, for a certain type of element or a certain type of isotope of an element, there's some probability that one of them will decay.

That, you know, maybe this guy will decay this second. And then nothing happens for a long time, a long time, and all of a sudden two more guys decay. And so, like everything in chemistry, and a lot of what we're starting to deal with in physics and quantum mechanics, everything is probabilistic. I mean, maybe if we really got in detail on the configurations of the nucleus, maybe we could get a little bit better in terms of our probabilities, but we don't know what's going on inside of the nucleus, so all we can do is ascribe some probabilities to something reacting.


Doesn’t Carbon-14 Dating Disprove the Bible?
