Is Technetium Tc 99m Albumin Safe in Breastfeeding

I am a breastfeeding mother and i want to know if it is safe to use Technetium Tc 99m Albumin? Is Technetium Tc 99m Albumin safe for nursing mother and child? Does Technetium Tc 99m Albumin extracts into breast milk? Does Technetium Tc 99m Albumin has any long term or short term side effects on infants? Can Technetium Tc 99m Albumin influence milk supply or can Technetium Tc 99m Albumin decrease milk supply in lactating mothers?

Information in this record refers to the use of technetium Tc 99m aggregated albumin (Tc 99m albumin colloid; Tc 99m microalbumin; Tc 99m HAM) as a diagnostic agent. The International Commission on Radiological Protection states that breastfeeding should be interrupted for 12 hours after administration of Tc 99m HAM.[1] 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.[2][3][4] Mothers need not refrain from close contact with their infants after usual clinical doses. However, reducing close contact with the child to the least possible time for 6 hours following injection of the radiopharmaceutical, will ensure that the exposure is "as low as reasonably achievable". Mothers concerned about the level of radioactivity in their milk could ask to have it tested at a nuclear medicine facility at their hospital. When the radioactivity is at a safe level she may resume breastfeeding. A method for measuring milk radioactivity and determining the time when a mother can safely resume breastfeeding has been published.[5] For nursing mothers who work with Tc 99m substances in their workplace, there is no need to take any precautions other than those appropriate for general radiation protection.[6]
