摘要

This document is the final report of the laboratory development of a method for determining the specific activity of the exp 129 I emitted from a nuclear fuel reprocessing plant. The technique includes cryogenic sample collection, chemical form separation, quantitation by gas chromatography, and specific activity measurement of each chemical species by negative ionization mass spectrometry. The major conclusions were that both organic and elemental iodine can be quantitatively collected without fractionation and that specific activity measurements as low as one atom of exp 129 I per 10 exp 5 atoms of exp 127 I are possible.
