RADIOACTIVITY: I'm hearing a lot on the press about Japan giving "iodine" to people who have some risk of exposure to radioactivity. This is a totally new area for me - I am not familiar with this treatment at all. Can you check and find out what form the iodine is actually in, and whether there are any possible complications from using it? That would be helpful to know.
Hopefully this answer helps:
Why I know what I know:
At one time I was a Medic on a SAC base (Strategic Air Command - the B-52's with the big bombs). I was on the NBC (Nuclear, Biological, Chemical) warfare team and received lots of interesting training.
Later on - while a firefighter and a reserve LE Deputy I attended more CBRN (Chemical, Biological, Radiological, and Nuclear) accident/incident classes - basically re-learning what I had been taught before)
I-131 is a radioactive isotope of I (Iodine) formed during the explosion of an atomic bomb OR during a severe accident at a nuclear reactor. It has a half-life of 8 days. SO 64 days after 100 grams is formed you have 0.390625 grams left.
(
amount decays by 1/2 per half-life.
creation 100g,
8 days later 50 gram,
8 days later 25 gram,
8 days later 12.5 gram,
8 days later 6.25 gram,
8 days later 3.125 gram,
8 days later 1.5625 gram,
8 days later 0.78125 gram,
8 days later 0.390625 gram,
you get the idea.
)
I-131 is treated by the body just as if it were normal Iodine and will be absorbed into the thyroid. Get too much - your thyroid can die. Get a little bit - your thyroid is subject to a greater chance of a cancer.
To prevent I-131 uptake by the thyroid, you have to flood it with non-radioactive Iodine.
There are two types of Iodine available:
- KI (Potassium Iodide) and
- KIO3 (Potassium Iodate)
that can be used to saturate your thyroid.
<< As a FYI, SSKI drops is a super saturated solution of potassium iodide>>
There seems to be some controversy/intense discussion concerning whether KI or KIO3 is best.
We were always issued KI pills.
Concerning which is best, I have read the papers quoted and for the most part MIS-quoted.
I am satisfied that either will do the job and that both have their downsides.
Neither downsides - in my opinion - are as bad as thyroid problems.
KI4U.com is a good place to read up on it.
Also the Medical Corps website is a good place to read up on it.
As it stands right now, based on what I know and for my location, I am not worrying about saturating my thyroid. You may want to check with local authorities for your area.
If you have any questions, concerns, comments, or just want to chat more about this, please do so.
