Although it may be seen as outdated, many labs still use Libby's half-life in order to stay consistent in publications and calculations within the laboratory.

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.

Carbon dioxide also permeates the oceans, dissolving in the water.

In contrast, living material exhibit an activity of 14 d/min.g.

Thus, using Equation \(\ref\), \[\ln \dfrac = (1.21 \times 10^) t \nonumber\] Thus, \[t= \dfrac = 2 \times 10^3 \text \nonumber\] From the measurement performed in 1947 the Dead Sea Scrolls were determined to be 2000 years old giving them a date of 53 BC, and confirming their authenticity.

Before Radiocarbon dating was able to be discovered, someone had to find the existence of the C isotope.

In 1940 Martin Kamen and Sam Ruben at the University of California, Berkeley Radiation Laboratory did just that.

The highest rate of carbon-14 production takes place at altitudes of 9 to 15 km (30,000 to 50,000 ft).

At high geomagnetic latitudes, the carbon-14 spreads evenly throughout the atmosphere and reacts with oxygen to form carbon dioxide.

Carbon dating, also known as radiocarbon dating, is a method of estimating the age of carbon-bearing materials up to 60,000 years old.

However, it is also used to determine ages of rocks, plants, trees, etc. When the sun’s rays reach them, a few of these particles turn into carbon 14 (a radioactive carbon).

Once an organism is decoupled from these cycles (i.e., death), then the carbon-14 decays until essentially gone.

The half-life of a radioactive isotope (usually denoted by \(t_\)) is a more familiar concept than \(k\) for radioactivity, so although Equation \(\ref\) is expressed in terms of \(k\), it is more usual to quote the value of \(t_\).

The entire process of Radiocarbon dating depends on the decay of carbon-14.
