摘要：

Recent topical measurements performed in the Ogoya Underground Laboratory are briefly summarized. The paper deals mainly with the following topics: measurements of variations of airborne Rn-222, Pb-210, Po-210 and Be-7 with high temporal resolution, the depth profile of Cs-137 in Pacific water collected in 1957; cosmic-ray-induced Na-22 in surface air, rain, river and lake waters; Eu-152 in granite exposed to the Atomic Bomb in Hiroshima in 1945; and depleted uranium used in the Iraq War 2003.
