https://doi.org/10.1007/978-3-030-05511-0e used as an accurate index of the counting efficiency on one of them. This method saves considerable time compared with the conventional internal-standard method and appears to be of equal or greater accuracy.

The Radiation-Induced Addition of Tritium to Unsaturated Systems of tritium. In some cases, which will be discussed later, this can be used to advantage. However, for most applications it would be desirable to prevent the addition of tritium to unsaturated systems.

Experiences with Tritiated Compounds Prepared by Exposure to Tritium Gaspounds, a partly saturated polycyclic structure, a poly-basic amino acid, a porphyrin-like structure, a sugar phosphate, and, in confirmation of an earlier report, [1] sucrose. Conditions prevailing during the tritiation of these compounds, as well as specific activities attained, are listed in Table I.

The Gas Exposure Technique for Tritium Labelinghave been obtained, for example, in hydrocarbons, carbohydrates, sterols, and peptides. Results of some degradative studies indicate that compounds labeled by this technique may contain tritium at all possible positions, but at a nonuniform distribution.
