We established the radiocarbon dating of ancient iron articles by accelerator mass spectrometer (AMS) method, and did that I gave the direct generation value to an iron articles with a purpose. The efficiency was good and extracted it in high purity without letting you pollute the carbon which was inherent in an iron sample and inspected the effectiveness of the radiocarbon dating of ancient iron articles.Through a forge blacksmithing experiment, I did the ^<14>C dating by AMS of the charcoal which we used for blacksmithing experiment and the iron sample provided by the blacksmithing process. We examined a generation value afterwards. As a result, the carbon history in iron showed the generation almost same as charcoal before using it for a blacksmithing experiment. Therefore I understood that a carbon history in iron was moved by charcoal used in the case of blacksmithing.Carbon in the ancient iron artifacts takes influence to carbon of the charcoal which I used for every each production process. And I was direct and was able to give the generation to an iron articles so that a carbon history in an iron articles was substituted for by doing the ^<14>C dating. In addition, I was able to identify the effectiveness as legitimacy of doing the ^<14>C dating of the iron articles.However, the dispersion that exceeded a measurement error in the ^<14>C dating of the sample which I measured this time, Carbon isotope discretion produces it to some samples, some time differences were able to be considered in a ^<14>C dating of charcoal used for blacksmithing and made iron articles.Therefore in order to raise an exact degree of the ^<14>C dating of the iron articles of the ancient times, the need that I elucidated produced these phenomena in future.
