Nuclear radiation carbon dating
From the discovery of Carbon14 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 onehalf of a sample to decay is called the halflife of the isotope, and it’s given the symbol: It’s important to realize that the halflife 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 halflife of 5730 / 40 years for Carbon14.
Using this hypothesis, the initial halflife he determined was 5568 give or take 30 years.
