  • This paper reports the application of radiocarbon wiggle-matching for Korean wooden artifacts such as buildings and Buddhist statues for precise dating. Nine quinquennial (every five-year) samples of 41 years (AD 1250-1290) for AMS radiocarbon measurements were prepared from a wooden board used for the Main Hall at Jeongsusa (temple) in Kangwhado, Korea, which was dendrochronologically dated. The 95.4% confidence interval of radiocarbon dating prior to wiggle matching was 113.3 year in average. When wiggle-matching technique was applied, it became 20 years, 5.7 times smaller than that produced without wiggle matching. The results indicated that wiggle-matching technique using the calibration curve for northern hemisphere (IntCal04) can produce precise dates for Korean wooden artifacts, at least, for the $13^{th}$ century.

  • 문화재의 연대를 측정할 때 널리 사용하고 있는 방법은 방사성탄소측정법인데 탄소를 함유하고 있는 유기물(목재,목탄,뼈,패각류 등)을 대상으로 연대를 측정한다. 그런데 최근에는 기기의 발달로 방사성탄소의 개수를 직접 헤아려서 연대를 측정하는 가속기질량분석계를 사용하고 있다.

  • The purpose of this study was to analyze radiocarbon dating, using wiggle match, of a wooden board from Yeongheung-do shipwreck excavated from Yeongheung-do in Incheon Ongjingun. The result of wiggle matching for 5 decennial tree-ring block samples of the hull bottom board produced ${\pm}2{\sigma}$ radiocarbon date (95.4% confidence interval) as A.D. 710~730 or A.D. 750~774. It indicated that the Yeongheung-do shipwreck belonged to the early or middle of the 8th century. Radiocarbon dating results confirmed the date speculated by archaeologists according to ship structure and pottery style.

  • The purpose of this study was to carry out radiocarbon dating using a wiggle match, of wooden boards and grains from the Mado shipwreck No. 4, which was excavated from Mado in Taean-gun, Chungcheongnam-do. The result of the wiggle matching for four decennial tree-ring samples of the stern plank produced a ${\pm}2{\sigma}$ radiocarbon date (95.4% confidence interval) of A.D. 1337-1356 or A.D. 1412-1429. The grains produced a ${\pm}2{\sigma}$ radiocarbon date (95.4% confidence interval) of A.D. 1415-1455. This indicated that the Mado shipwreck No. 4 belonged to the early or middle of the 15th century. These radiocarbon dating results correlate with the date that was speculated by archaeologists according to the ship's structure and ceramic style.

  • The purpose of this study was to analyze AMS radiocarbon dating, using wiggle match, of a charcoal column excavated from a fired dwelling site (ra-#8) at the Pungnaptoseong earthen wall made in Baekje era. The result of wiggle matching for 6 decadal single-ring samples of the charcoal produced ${\pm}2{\sigma}$ radiocarbon date (95.4% confidence interval) as A.D. 190~280. It indicated that the dwelling site (ra-#8) belonged to the early and middle of the 3rd century. Radiocarbon dating results confirmed the date speculated by archaeologists according to dwelling structure and pottery style.

  • This study aimed for species identification and tree-ring dating and radiocarbon dating of wooden warehous materials excavated from Baengnyeongsanseong in Geumsan. The species of 83 wooden materials were identified as 38 Platycarya spp., 34 Cerris Section, 8 Prinus section, 2 Hard pine, and 1 Kalopanax pictus. After cross-dating of 5 Cerris Section samples with the TSAP program, one Cerris Section chronology (GSQU 1S) was constructed. To identify the exact date, one material which show many tree-ring (GSQU 05) was analyzed by radiocarbon dating using wiggle match. As a result of radiocarbon dating, the outermost edge of east beam (GSQU 05) was found to be A.D. 575-655 or A.D. 665-685. The radiocarbon dating of wooden warehouse material was consistent with the archaeologically estimated date.

  • It was estimated that wooden warehouses excavated from Bongseon-ri site in Seocheon were built around the 5th century according to the soil layers and construction methods of earthen structures. In order to identify the exact date, three wooden materials (BSMG 01, 06, and 12) from wooden warehouses were analyzed through radiocarbon dating using wiggle match. The outermost ring of BSMG 01 produced a radiocarbon date (95.4% confidence interval) of AD 431~551, BSMG 06 produced a date of AD 460~570, and BSMG 12 produced dates of either AD 240~430 or AD 490~510. The common age of the three wooden materials was identified as AD 490-510 and coincided with the original estimated archaeological age. Therefore, this study proved the accuracy of radiocarbon dating using wiggle match.

  • Absolute ages for three pieces of organic materials such as wood and shell were determined with radio-carbon concentrations and two potsherds with thermoluminescence measurements. Radiocarbon contents of each sample were compared with those of modern standard oxalate(NBS SRM4990C) and calculated radiocarbon ages of them. Quartz grains with diameter of $90\sim150{\mu}m$ were extracted from potsherds and used for measuring the archaeodose. Annual dose were calculated with measuring the alpha count rates and water contents and analysing $K_2O$ concentration of both potsherds and soils. Radiocarbon ages of organic materials were in the ranges of $4\sim2C$ BC and Quartz grain techniques for thermoluminescence dating showed 170 BC ud 210 BC respectively. It was found that the results of radiocarbon dating and TL dating were accorded with each other. But the deviations of TL dating have shown 13% and 20% respectively. It need to reduce the deviations.
