Define radiometric dating techniques
The discovery allowed him to correctly date a piece of wood from an Egyptian tomb that was known to be about 4,600 years old.
In the last 40 years, radiocarbon dating has been used on more than 100,000 samples in 80 different laboratories.
Boltwood (1870–1927) suggested that knowledge of radioactivity might be used to determine the age of Earth's crust.
The limitations of radiometric dating can be split into two general categories, analytical limitations and natural limitations.
However, once the organism dies, the supply stops and the carbon-14 in its body begins to decrease according to its own rate of decay.
Libby realized that this could be a practical dating tool.
When a substance is described as radioactive, it means that at the subatomic (relating to parts of an atom) level, some parts of it are unstable.
When a substance is described as unstable, it means that it has a tendency to break down or decay.
