Is Rubidium Rb-82 Safe in Breastfeeding

I am a breastfeeding mother and i want to know if it is safe to use Rubidium Rb-82? Is Rubidium Rb-82 safe for nursing mother and child? Does Rubidium Rb-82 extracts into breast milk? Does Rubidium Rb-82 has any long term or short term side effects on infants? Can Rubidium Rb-82 influence milk supply or can Rubidium Rb-82 decrease milk supply in lactating mothers?

Information in this record refers to the use of Rubidium Rb-82 as a diagnostic agent. No information is available on the use of Rubidium Rb-82 during breastfeeding. The manufacturer recommends withholding breastfeeding for 1 hour after a diagnostic dose of Rubidium Rb-82.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 guideline is followed. 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.[1][2][3]
