MIBG cannot be inhaled by those present in the room during the infusion or after the patient has been treated. Some of the MIBG will go to the neuroblastoma cells and the rest leave the body in the urine and other bodily fluids like saliva and stool. But most will be eliminated through the urine.
The Radiation Safety Team will monitor the radiation levels in the room and in the patient every day.
A patient is typically considered safe for discharge when the radiation level measured at one meter distance from the patient is 2mREM/hr or less.
