[ RadSafe ] 14000 deaths

Tue Dec 20 16:44:24 CST 2011

Hi John,

Having just undergone a radioiodine thyroid ablation end of August, and calculating the hourly radiation exposure that was also used to calculate the % uptake over the same time, I know that the KI needs to be taken early to block the amount of radioiodine potential uptake. I don't have any reference off the top of my head but I expect I can find some data in the literature.

Happy Holidays!

Sandy

Sandy and Patricia

It is my understanding that we (and  mammals) all need iodine to live. Books have been written about this!

Our thyroid is the reservoir that stores it and it has a limited capacity. 
If we what to decrease the amount of radioactive iodine that is "taken up" 
we give large amount stable iodine before the exposure because the thyroid will then be "full" and can not take in any more.

Merry Christmas and a Happy New Year to you and all radsafers.

Sandy. Can you give a reference for "individuals who are allergic to iodine"?

Unless one applies a "population dose" model for iodine exposure.  In this model, you would take the amount of iodine consumed by the entire population, including people who through induced but misguided panic consumed large quantities of KI (often purchased online at enormously inflated prices).  Then divide by the number of people, and assume that everyone received the same amount, even though that clearly wasn't the case. 
Then, to be "conservative" (which in this case has an undefined meaning, but is used to imply "better"), one can assume that more people are allergic to iodine than the statistics would support, that their reactions are both more sever and less well characterized than is normally believed (indeed, mimicking conditions that are usually attributed to other things, and were pre-existing), and that there is a conspiracy to hide all this.

Or you could just make it up.  Whatever.

Patricia,

While there are individuals who are allergic to iodine, I would not expect that KI pills have anything to do with the asinine conclusions reported about 14,000 deaths. Perhaps this was addressed but I don't recall any discussion that states a significant amount of KI pills were distributed to the population. Unless the pills were distributed within a specific amount of hours prior to the intake of I-131, the thyroid would have been not been protected by the KI, and of course the individuals who are allergic would not have been as affected.

Regards,

Sandy

any chance there were deaths or complications from taking iodine tablets or other preventative measures?
