Is Sodium Chromate Cr 51 Safe in Breastfeeding

I am a breastfeeding mother and i want to know if it is safe to use Sodium Chromate Cr 51? Is Sodium Chromate Cr 51 safe for nursing mother and child? Does Sodium Chromate Cr 51 extracts into breast milk? Does Sodium Chromate Cr 51 has any long term or short term side effects on infants? Can Sodium Chromate Cr 51 influence milk supply or can Sodium Chromate Cr 51 decrease milk supply in lactating mothers?

Information in this record refers to the use of sodium chromate Cr 51 as a diagnostic agent. No information is available on the use of sodium chromate Cr 51 during breastfeeding. The manufacturer recommends withholding breastfeeding after a diagnostic dose of sodium chromate Cr 51, but does not provide a specific duration. The long biological and physical half-lives of chromium may preclude resumption of breastfeeding of the infant. Mothers concerned about the level of radioactivity in their milk could ask to have it tested at a nuclear medicine facility at their hospital and when the radioactivity is at background levels they may safely resume breastfeeding. A method for measuring milk radioactivity and determining the time when a mother can safely resume breastfeeding has been published.[1]
