Naming Guidelines
Superscripts should not be used in either Fully Specified Name, Preferred Term, or Synonyms.
Parentheses should be used to delineate the atomic number and chemical symbol from the rest of the terming, this aligns with INN.

Naming Guidelines
Superscripts should not be used in either Fully Specified Name, Preferred Term, or Synonyms.
The Fully Specified Name should explicitly state that a component was “labeled” by a radioisotope in the FSN. Do not use “with”, “and”, or “tagged”.
Omit the word “labeled” from the PT, keep a synonym to match the FSN.
