Vermilion was collected from powerful people's mounds of places of Japan Sea coast depending on the period from the decline of the Yayoi to Kofun and was measured sulfur isotope ratio (δ34S value), and compared the value obtained from cinnabar ores of three Japanese mines, Niu, Yamato-suigin, and Sui, and two Chinese mines, Wanshan and Xunyang, which were selected from old records. The vermilion of the late Yayoi period, the 1st to 2nd century A.D., was from China, and the vermilion of the early Kofun period, from the late 3rd century A.D., was from Japan. During the late Yayoi and early Kofun periods, the 3rd century A.D., the vermilion showed the middle of the shift of Japanese cinnabar. It is concluded that the measurement of sulfur isotope of vermilion is an effective method for the determination of original sources of vermilion.

Environmental standards of nuclear waste disposal, are determined from the accident victim of exposure data, such as animal experiments and war and nuclear test. They are all in a short period of time of exposure, is the impact data on the human body. As exposure example of the long-term, there is an exposure of local residents such as natural radiation exposure and radiation dose especially large Radium Hot Springs. Low-level radiation of these day-to-day exposure shows that it is clear from the fact of more than 1000 years that there is a health-promoting effects, not harmful. Japan of Radium Hot Springs (Tamagawa hot spring) there is a history of 1200 years. Overseas there is a Karlovarsky kraj hot spring of Czechoslovakia that Madame Curie was built. This hot spring there is a history of about 500 years. In addition, hot spring with mixed low-level radium utility from ancient times of BC 100 years, there is a fact that was not the environment pollution. In other words, from the history of the human race, which has been living under the low-level radiation, for establishing more appropriate environmental standards of low-level radiation emitted from nuclear waste, we investigate the historic hot springs.
2 0 0 0 OA 同位体分析法から見た墳墓出土朱の産地変遷-大和政権による朱の政治的利用-
弥生時代後半から古墳時代に重点を置き、墳墓より出土した朱の産地推定を硫黄・鉛・水銀同位体分析から行った。その結果、北部九州では古墳時代に入っても中国産朱と思われる朱が一部の墳墓に用いられていたが、それ以外の地域では古墳時代に入る前から国内産の朱が墳墓に使用されていた可能性が高く、古墳時代前期には東北地方まで畿内産の朱がもたらされたと考えられる。以上より、朱の同位体分析により古墳時代黎明期の権力推移が考察され、考古学分野に一石を投じることができたと考える。
