Battelle Memorial Institute Columbus. (LLNL) to extract carbon from modern steels and ancient iron artifacts. The applicability of the iron dating technique was severely limited by this large sample. Archaeologists have conducted fieldwork geared to the study of ancient technologies in a cultural context and have drawn on the laboratory analyses developed by materials scientists as one portion of their interpretive program.

Recent advances include simplification in sample preparation and reduction in sample size for accelerator mass spectrometry measurements, and the potential use of rust as a viable source of material for radiocarbon dating. PDF | During the late s, N. J. van der Merwe () obtained 14 C measurements on 11 iron pieces, ranging in carbon content from medium carbon . Radioactive carbon, that is 14 C, occurs naturally and is formed continuously in the atmosphere.

Because the decay rate of 14 C is known the half-life is 5, yearsby using mass spectrometry to measure the amount that remains in a sample it is therefore possible to determine the age of that sample. The radioactive 14 C decays at a known rate back to nitrogen and so the ratio of 14 C to the other forms of carbon continuously decreases with time.
