Re: Potassium Iodide administration



This sounds very ill-advised, to me. If the investigators are receiving
significant intakes of radioiodine, procedural, or engineering, changes
should be made to control/reduce them. Physiologic changes could result from
the long-term, routine, consumption of stable iodine, at quantities greatly
in excess of those required by the normal metabolism (150 ug/day). That is
what would be required to reduce their uptake. Large quantities of stable
iodine (>100mg) are given, to BLOCK the thyroid, when an acute intake that
may result in deterministic effects, or greatly increase the risk of
stochastic effects, has occurred (or is likely to occur). Where are they,
relative to your ALARA levels, and why?
