A review on 129I analysis in air

A review of literature focused on 129I determination in air is provided. 129I analysis in the environment represents a vital tool for tracing transport mechanisms, distribution pathways, safety assessment and its application as environmental tracer. To achieve that, specific chemical extraction methods and high sensitivity analytical techniques have been developed. This paper is intended to give an overview about the sample collection, extraction and distribution of 129I in the air. Sensitivity of available measurement techniques for the determination of 129I is compared. The article also provides the summary of current worldwide distribution of 129I in air and respective radiation exposure of man.
