High-resolution measurements of temporal variations of airborne <SUP>210</SUP>Pb and <SUP>7</SUP>Be were performed by ultralow background γ-spectrometry at Ogoya Underground Laboratory (OUL). Moreover, high-resolution measurements of <SUP>210</SUP>Po were also made by α-spectrometry at Low Level Radioactivity Laboratory (LLRL). In this paper, the results focusing mainly on cyclic variation with ∼1 week period observed in winter season, and the high resolution measurements conducted at the time of approach of typhoon and Kosa events are reported.
