Information Notice 99-11, "INCIDENTS INVOLVING THE USE OF RADIOACTIVE    
IODINE-131," was issued on April 16, 1999.                               
                                                                         
This notice was issued to all medical licensees to alert them to recent  
incidents that resulted in unintended radiation doses to humans, as a    
result of the administration of radioactive iodine.  These cases         
illustrate the need for communication and coordination between the       
authorized user and the referring physician.  They also illustrate the   
importance of verifying correct dosages and patient identity before      
administration.
