Dear Sandy:

Most diagnostic thyroid scans use I-123 NaI, not NaI.  Most 
metastatic surveys use I-131 NaI, although some use I-123.  Which are 
you talking about?  Therapeutic thyroid ablation can be for Graves' 
disease or differentiated thyroid cancer.  Which do you want?  For 
dosimetry, use RADAR or ICRP #53.

Ciao, Carol
