• This survey of the environmental gamma rays was made in a littoral region of Volcano Bay andaround Mount Usu. The dose rate levels of the environmental gamma rays were estimated from thesurvey results that measured with a portable germanium detector and a spectrometer. A car-bornsurvey and a spot survey were made by these measurement systems installed in a car. The variationof the total absorbed dose rate was found to be originated mainly by the variation of the Th-232 seriesnuclides. In some situations, it was found to be caused by the variation of the U-238 series nuclides.A half year after an eruption of Mount Usu, large and random variations of a K-40 dose rate wasmeasured at some points around a volcanic crater. Although 2 years after the eruption, it wasconfirmed those variation had become fairly steady.
