USAN assigned to radioactive pharmaceutical

The United States Adopted Names (USAN) applicable to radioactive pharmaceuticals are composed of the names of the basic compound serving as the carrier for the radioactivity, the symbol for the radioactive isotope, and the atomic weight (since several radioactive isotopes of a given element may be in use--see listing under iodine). The following listing of nonproprietary names (shown in boldface type) is arranged in alphabetical order according to the English name of the radioactive element. The isotopes of hydrogen are listed under their specific names, deuterium and tritium. Radioactive pharmaceuticals are often supplied by the manufacturers under a designation equivalent to the adopted nonproprietary name and are listed as such; specific trademarks are given in brackets when they exist. Basic information relative to these lists was given in the editorial that accompanied the first such listing.
