The AMS facility at the Japan Atomic Energy Research Institute (JAERI)

A new AMS facility has been set up at the Japan Atomic Energy Research Inst itute (JAERI) in 1997 and C-14 as well as I-129 Will be used for marine env ironmental studies. The 3 MV AMS system is able to perform high-precision 1 4C as well as heavy element AMS. The C-14-AMS section of the system has bee n accepted and its precision is comparable to other high-precision C-14-AMS systems. The heavy element section is under preparation and close to accep tance. A sample preparation system for the extraction of dissolved inorgani c carbon (DIC) from seawater has been built up and tested. An accuracy chec k of the sample preparation system and the 14C-AMS system has been carried out with internationally accepted C-14 Standard material. (C) 2000 Elsevier Science B.V.
