Measurements were made of the activity in samples of breast milk obtained from a patient with postpartum thyroiditis following administration of (/sup 123/I)sodium iodide and subsequently (99mTc)pertechnetate 24 hr later. Both /sup 123/I and 99mTc were found to be excreted exponentially with an effective half-life of 5.8 hr and 2.8 hr, respectively. Less than 10% of the activity was incorporated into breast-milk protein. After administration of (/sup 123/I)sodium iodide breast feeding should be discontinued for 24-36 hr to reduce the absorbed dose to the child's thyroid.
