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]
