Learning on ScreenRadiocarbon Dating for Archaeology (3 Parts)
- Synopsis
- 1: Introdes radioactivity. An experiment using 56Mn shows how the decay of radioactive isotopes can be detected. Introduces the concept of half-life. Explains the theory behind radiocarbon measurements.
2: Shows the two main techniques used for counting carbon-14 samples: gas counting and liquid scintillation counting. Discusses the chemical processes involved in preparing a sample and follows a sample from its combustion to carbon dioxide to the counting in a liquid scintillation spectrometer.
3: Looks at the types and quantities of material needed for radiocarbon dating, explains what chemical treatments are used to remove contamination, and discusses how the result is presented. Includes explanation of the error term c13C and calibration of results. - Language
