9.5 Iodine Therapy Requirements and Precautions

The following steps are required for individuals involved with the preparation and/or administration of radioiodine therapy doses:

  • Obtain a thyroid bioassay within one to four days following the administration.  Contact EHS to schedule this bioassay. 
  • Therapy dose preparations involving aqueous solutions of sodium iodide are to be performed in an operating fume hood with a current EHS airflow performance sticker. 
  • Always wear disposable gloves and a lab coat when preparing or administering I-131.
  • Monitor hands, feet and clothing for contamination after each procedure prior to leaving the area.
  • Transport therapy doses in shielded containers.  Following administration, treat the outer surface of the shielded dosage container as contaminated until proven otherwise by a radiation survey.
