Isotopic investigations for the origin of relic from the Matsusaki site, Japan.
We measured the environmental radioactivity and isotope ratio, (87)Sr/(86)Sr ratio, (234)U/(238)U, delta(13)C, and (228)Ra/(226)Ra activity ratio, of adhesion that adhered to a wooden tubing vessel obtained from the Matsusaki site, one of the salt-production sites where Moshio is manufactured, in Aichi Prefecture, Japan. The environmental radioactivity and isotope ratio verified that the adhesion originated from the seaweed and/or sea grass.
