Nuclear radiation carbon dating


Carbon-14 is first formed when cosmic rays in the atmosphere allow for excess neutrons to be produced, which then react with Nitrogen to produce a constantly replenishing supply of carbon-14 to exchange with organisms.Scientists look at half-life decay rates of radioactive isotopes to estimate when a particular atom might decay.



From the discovery of Carbon-14 to radiocarbon dating of fossils, we can see what an essential role Carbon has played and continues to play in our lives today.It takes a certain amount of time for half the atoms in a sample to decay.It then takes the same amount of time for half the remaining radioactive atoms to decay, and the same amount of time for half of those remaining radioactive atoms to decay, and so on. The amount of time it takes for one-half of a sample to decay is called the half-life of the isotope, and it’s given the symbol: It’s important to realize that the half-life decay of radioactive isotopes is not linear.From that point on, scientist have used these techniques to examine fossils, rocks, and ocean currents and determine age and event timing.

Throughout the years measurement tools have become more technologically advanced allowing researchers to be more precise and we now use what is known as the Cambridge half-life of 5730 /- 40 years for Carbon-14.

Using this hypothesis, the initial half-life he determined was 5568 give or take 30 years.
