Testing the radiocarbon dating method

The radiocarbon method was developed by a team of scientists led by the late Professor Willard F.

Libby of the University of Chicago after the end of World War 2.

In the 1940s, scientists succeeded in finding out how long it takes for radiocarbon to disappear, or decay, from a sample of carbon from a dead plant or animal.

Willard Libby, the principal scientist, had worked in the team making the nuclear bomb during World War 2, so he was an expert in nuclear and atomic chemistry.

After twice that time (about 11000 years), another half of that remaining amount will have disappeared.

After another 5568 years, again another half will have disappeared.

Because carbon is very common on Earth, there are alot of different types of material which can be dated by scientists.

Below is a list of the different kinds of materials which can be dated: Libby tested the new radiocarbon method on carbon samples from prehistoric Egypt whose age was known.

The person who wrote these words lived in the 1800s, many years before archaeologists could accurately date materials from archaeological sites using scientific methods.The half-life refers to the amount of time it takes for half the radiocarbon in a sample of bone or shell or any carbon sample to disappear.Libby found that it took 5568 years for half the radiocarbon to decay.The job of a radiocarbon laboratory is to measure the remaining amounts of radiocarbon in a carbon sample.This is very difficult and requires a lot of careful work to produce reliable dates.

Rasmus Nyerup's quote reminds us of the tremendous scientific advances which have taken place in the 20th century.

  1. In fact, because of concerns about trichinosis from pork, it makes a lot more sense in my opinion to buy cured bacon and other pork products. Have I changed your mind about the safety of eating bacon?
