Is Cromato sodico (51 Cr) Safe in Breastfeeding

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

Information in this record refers to the use of Cromato sodico (51 Cr) as a diagnostic agent. No information is available on the use of Cromato sodico (51 Cr) during breastfeeding. The manufacturer recommends withholding breastfeeding after a diagnostic dose of Cromato sodico (51 Cr), 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]
