RE: I-124 Intake Retention Values



Joey



The usual procedure is to assume that iodine is retained in the thyroid with

a half-life of 80 days (ICRP Pub. 54). Since the half-life of I-124 is 4.2

days, the retention is ~4.1 days.

A collegue of mine is looking for the thyroid retention values for I-124.

Does anyone have these or know where they can be obtained?
