Is N-13 Ammonia Safe in Breastfeeding

I am a breastfeeding mother and i want to know if it is safe to use N-13 Ammonia? Is N-13 Ammonia safe for nursing mother and child? Does N-13 Ammonia extracts into breast milk? Does N-13 Ammonia has any long term or short term side effects on infants? Can N-13 Ammonia influence milk supply or can N-13 Ammonia decrease milk supply in lactating mothers?

Information in this record refers to the use of N-13 Ammonia as a diagnostic agent in PET scans. No information is available on the use of N-13 Ammonia during breastfeeding. The Society for Nuclear Medicine and the International Commission on Radiological Protection states that breastfeeding need not be interrupted after administration of N-13 Ammonia,[1][2] although the manufacturer recommends withholding breastfeeding for 2 hours. This length of time is greater than 10 half-lives of the radioisotope, so the nursing infant should not be exposed to radiation if this the 2-hour time period is used. The mother can nurse just before administration of the radiopharmaceutical. If the mother has expressed and saved milk prior to the examination, she can feed it to the infant during the period of nursing interruption.[3][4][5] Milk that is pumped by the mother during the time of breastfeeding interruption can either be discarded or stored and given to the infant after 10 physical half-lives, or about 2 hours, have elapsed. Nursing mothers should not work with radioactive substances used in PET scans in their workplace.[6]
