[ RadSafe ] Radioiodinations

[Flanigan, Floyd]

It has always been my understanding that Iodine, regardless of the form,
is absorbed by the thyroid. I am unaware of any other organ with a
higher affinity for Iodine than the thyroid.

In a past life I worked in University research settings, and the RSO had
set up a Thyroid counting station for our researchers to come in once a
week when using I-125. I question whether checking the reading at the
thyroid was correct. Most of the I-125 we got in was in the form of a
radiolabeled chemicals such the DNA precursurs. My understanding of
uptake
is that the moleule will follow its pathway differently than the
element.
i.e. instead of going to the thyroid like iodine would,  it might go
whole
body or concentrate in another specific organ. Is my thinking correct?
