Abstract
The Uppsala tandem accelerator system has been improved for application in 129I AMS. At present routine measurements at 3% relative error are performed on water samples. The accelerator mass spectrometry (AMS) system background is < 10-14, but when carrier and chemical processing are included the background corresponds to 129I/127I = 10-13. Niobium is found to be the most appropriate AgI binder material. The AMS spectrometric design, present performance and some 129I environmental applications are presented.
