When objects of the Old Kingdom and Middle Kingdom of Egypt yielded carbon dates that appeared roughly comparable with the historical dates, Libby made his method known.

With initial large margin of error and anything that did not square with expectation, judged as “contaminated,” the method appeared to work and was hailed as completely reliablejust as the atomic clock is reliableand this nobody doubted.

The first lesson, Isotopes of Pennies, introduces the idea of isotopes.

The final lesson, Frosty the Snowman Meets His Demise: An Analogy to Carbon Dating, is based on gathering evidence in the present and extrapolating it to the past.

Radioactive tracers are substances that contain a radioactive atom to allow easier detection and measurement.

(Radioactivity is the property possessed by some elements of spontaneously emitting energy in the form of particles or waves by disintegration of their atomic nuclei.) For example, it is possible to make a molecule of water in which one of the two hydrogen atoms is a radioactive tritium (hydrogen-3) atom.

One would simply pass a Geiger counter over the plant at regular intervals and see where the water has gone. Radioactive tracers have applications in medicine, industry, agriculture, research, and many other fields of science and technology.And in the aftermath of the March 2011 earthquake and tsunami that struck Japan, a nuclear crisis raised fears about radiation and questions about the safety of nuclear power.­Nuclear radiation can be both extremely beneficial and extremely dangerous. X-ray machines, some types of sterilization equipment and nuclear power plants all use nuclear radiation -- but so do nuclear weapons.But as the method was refined, it started to show rather regular anomalies.First, it was noticed that, when radiocarbon dated, wood grown in the 20th century appears more ancient than wood grown in the 19th century.
