Radiocarbon ( 14 C) in natural samples undergoes changes due to variations in atmospheric CO 2 resulting from anthropogenic activities. To analyze the variation of the 14 C ratio in atmospheric CO 2 , deciduous tree leaves were collected in Gyeongju, a popular tourist city in South Korea. Leaf samples were collected from Prunus subg. Cerasus trees at five different sampling points throughout the city over 3 years (2018, 2020, and 2021). The 14 C data of the samples were categorized into three groups (downtown, rural, and tourist sites) and analyzed for variations among the different years. The 14 C ratio at downtown sites was stable after 2018, the rural site ratio increased between 2018 and 2020 and then decreased between 2020 and 2021, and the tourist site ratio increased after 2018. We theorize that the increased 14 C ratio at the tourist site was caused by a decrease in tourism after 2018
