For all the crazy, deep in the bunker, afraid of the world, psychotic survivalists that are popping iodine tablets like peanuts, here is an explanation of everything you could ever want to know about taking prophylactic iodine. :thumb: :
BuellerBueller, MikeK and a few others, brought up a couple of good questions about iodine.
Strangely good quality information is really not readily available on the internet (who would have thought THAT!)
OK, here’s the Iodine scoop in a nut shell:
KIO3 is Potassium Iodate.
It contains about 59% iodine by mass.
Most KIO3 formulations that are being sold offer 170mg/tablet
This gives a dose of iodine of about 100.9 mg per tablet
KI is Potassium Iodide.
It contains about 76.5% iodine by mass.
Most KI formulations that are being sold offer 130mg/tablet
This gives a dose of iodine of about 90.4 mg per tablet
- The Recommended Daily Allowance (RDA) of iodine is 0.150 mg/day
- The Upper Level safe range for iodine is about 1 mg/day.
This is not just something to ignore, this level of iodine in an average person who's body is naive to high doses of iodine in their diet WILL have medical ramifications :xeye:
The recommended Daily Allowance of iodine is 150 mcg (or 0.150 mg) The pharmacologic dose to treat medical conditions is a little under ten times that amount at 1.1 mg for an average sized adult male. Children MUST be given significantly less by ratio of their mass
Damage to the body can begin with the ingestion of as little as 3 mg/day of iodine.
Now, these tablets that are being sold are 33x the amount where an individual will likely begin to have an adverse systemic reaction. Below I have listed a few of the signs and symptoms that you can expect to experience with this level of iodine overdose.
- Abdominal pain
- Metallic taste
- Oral lesions
My eyes see a huge synergistic sequela from that above list:
If you add oliguria to any situation in which the heart is already compromised, you can begin to think along the lines of a cardiac event. Add additional fluid with extreme thirst, and you have the makings of a real problem.
High doses of iodine have been linked to papillary cancer :xeye:
Additionally, many individuals that are ingesting more than about 18mg of iodine per day can form a goiter :xeye:
Some people worldwide have diets that have up to four times that amount (80mg/day), but they are adjusted to that level all the way since childhood and have not mega-dosed themselves to that level in a day. Luckily, Japanese people living in the northeastern portion of Japan (the only people that have to worry about any radiation problems from the disaster in Japan) have these high levels from their normal diet high in seafood and kelp.
Why Would I want to Take Iodine Anyway?
One of the radioactive threats of a nuclear disaster is radioactive iodine. But this is also a tiny localized threat because the iodine has quite a short half-life of only 8 days. This means that in 8-days, one half of the amount would be atomically reduced to non-radioactive iodine. In 16-days, only 25% would remain radioactive. In a mere 24 days 12.5% on down halving every 182 hours. The radioisotope of iodine that is a problem is also not a significant by product in the fission of nuclear reactor fuel rods to start with, so the levels are going to be a minimal portion of any radiation problem.
Will Taking Iodine Protect Me From Other Radiation?
Unfortunately, no. The thyroid is a gland in the body (neck) that uses iodine to produce a few hormones that we need. This gland eagerly gobbles up the iodine it needs from whatever source is available, and if radioactive iodine is present in the blood, it will be taken up in the thyroid and used. During the time it is stored in the thyroid, the radiation will be hitting that glandular tissue. That is where the thyroid cancer could come from after exposure. Having iodine already in the bloodstream limits, by dilution, the amount of potentially radioactive iodine that potentially will be taken up by the thyroid. However, all other forms of radioactive material are not blocked by iodine because it is not part of this thyroid-iodine mechanism.
Now, the big question...
How Do I, as a Prepared Individual, Get Enough Iodine without getting sick
from these ridiculously high doses in the tablets?
Well, you could smash the tablets and eat about 1/20th of one to supplement your normal 600mcg (0.6mg) that you get from a normal diet in the USA.
Or, here are some foods higher in iodine to maybe add to your chill-out and relax menu this weekend.
- Yogurt will give you about 0.095 mg of iodine
- Beer :thumb: gives about 0.045 mg of iodine (more in the darker beers)
- Bacon :thumb: OK, not much but who cares : about 0.002mg per slice
- Shrimp & Lobster about 0.125mg per 100g serving
- Tuna has about 0.024 mg iodine per can
Eat a healthy diet, toss a few cans of tuna and a few yogurts on the menu plan. Go out for a lobster dinner with your loved ones. That is all that would ever be needed unless you are the character in Fallout 3 :
And PS: Sorry everyone for the grody pictures. I forget sometimes that most people don't stick their fingers into diseased bodies every day :
