Thus, as living things take in carbon, they inevitably will take up a small amount of radioactive carbon into their bodies.When these lifeforms die, they stop taking in new carbon.

The man's body was recovered and pieces of tissue were studied for their C content by accelerator mass spectroscopy.
The best estimate from this dating technique says the man lived between 33 BC. From the ratio, the time since the formation of the rock can be calculated.
Professor Willard Libby produced the first radiocarbon dates in 1949 and was later awarded the Nobel Prize for his efforts.
Radiocarbon dating works by comparing the three different isotopes of carbon.
However, scientists can look at the decay of other elements in these objects allowing them to date them up to 2.2 billion years.
Unlike people, you can’t really guess the age of a rock from looking at it.
Say for example that a volcanic dike, or a fault, cuts across several sedimentary layers, or maybe through another volcanic rock type.
Radioactivity and radioactive decay are spontaneous processes.
