| 抄録 | By the use of extremely background Ge detectors in Ogoya underground Laboratory (270 m water equivalent of depth), it became possible to detect extremely low levels of environmental radionuclides more than one order of magnitude lower than usual detector. In this study, it was tried to measure high resolution and simultaneous monitoring of airborne Pb-210, Po-210, Pb-212 and Be-7 (+Cs-137 and Na-22) at three monitoring points at LLRL in Tatsunokuchi, Hegura Island located 50 km from Noto Peninsula and 640m hjigh Shishiku Plateau located about 8 km from LLRL. Various interesting results on the concentrations and variation patterns of airborn radionuclides were obtained, particularly, during drastic meteorological changes such as the passage of cold front or typhoon and snow fall in winter season. |
