The exposure of organic compounds to tritium gas  has received considerable attention in the past few years and has become an accepted method for tritium labeling. Experience has confirmed the initial report that activities in the range of 1–100 mc/g are generally obtained by exposure to curie amounts of tritium for several days, and that labeling is accompanied by the formation of tritiated by-products of high specific activity. Information on the distribution of tritium in labeled products and on the nature of the by-products has also been accumulated. Results obtained are summarized here to provide a firmer basis for assessing the limitations and the area of usefulness of the method.
