RE: Draft FDA Guidance document on the use of KI

["Thomas J Savin " <tjsav@lycos.com>]

When patients are being diagnosed for pheochromasitosis they immediately, after the whole body scan are given KI. This is given for a week or slightly longer.  The biological half life of tracer iodine is about eight days (+/-) when given KI.  The point here being that giving KI immediately after a nuclear accident is a precautionary measure well worth it. The milk ingestion, etc. can also be somewhat taken care of by continuing the ingestion of KI tablets. This way all exposure pathways can be covered.
