Abstract
A method for determining129I in atmospheric air is presented. It consists of the following stages: sampling (of aerosol and gas fractions separately), preparation of a sample for irradiation in a reactor by a destructive distillation method, irradiation of samples in a reactor, radiochemical separation and130I activity measurements by slow coincidences. Iodine isotopes (including129I) in the atmospheric air have mostly been found in gas fractions (except132I). Gas compounds and percentages of radioactive and stable iodine isotopes coincide.
