Radiocarbon Dating and Chronological Modelling
Guidelines and Best Practice
This publication provides guidelines for good practice in the use of radiocarbon dating and chronological modelling in archaeology. It gives practical advice on the application of these methods within archaeological projects in England. It should be used in conjunction with advice given by radiocarbon laboratories and modelling specialists on specific projects, and may be adjusted in response to future scientific developments.
