Does it make sense to stock up on iodine?

It' s my understanding that in a worst case radiation exposure scenario, you want to take a big dose of iodine so your thyroid grand will fill up with the good stuff, and prevent the bad stuff from coming in.

Is this correct? If so, what's the dose? How long does iodine keep? Would kids get a smaller dose?

    One of the elements being released from the damaged Fukushima reactor complex is a radioactive version of Iodine, called Iodine-131. This radioactive kind of Iodine was also released during the Chernobyl disaster.

    For people in the immediate vicinity of the leaking reactor who ate foods contaminated by the radioactive iodine, there were negative health concequences. Most people were exposed by drinking milk from cows that had grazed on grass contaminated with the radioactive iodine. Particularly for children, being exposed to this kind of Iodine can increase the future chance of coming down with Thyroid cancer.

    Radioactive Iodine-131 is short lived, losing almost all of it's radioactivity within about 40 days (or five half-lives of 8 days).

    For those in Japan, nearby the Fukushima plant, taking non-radioactive iodine helps keep the radioactive version from being absorbed. This medicine isn't perfectly safe. People can develop allergic reactions to it, and if they overdose, people can die of heart arrhythmias.

    For someone in the United States (including California, Washington, Oregon and even Hawaii), the amount of radioactive Iodine reaching us is (at this point) too small to accept the risk of taking the medicine.

    It might be wise to avoid eating iodine-rich foods that are harvested or collected from the parts of the Pacific Ocean most showed by debris from the reactors--at least until about a Month and a half after the reactor leaks are all fixed.

    There is a limited supply of this medicine, due to the crisis. Please do not stockpile it, and keep it from reaching those (in Japan) who really, desperately need it right now. Stockpiling Potassium Iodide right now is both unnecessary and unethical.

    Don't stockpile iodine unless you plan on treating lots of cuts or using it to purify water. The form needed for your body is potassium iodide and you stand to cause overdose problems if you don't educate yourself or get professional advice. Already cases of poisoning are starting to show up in the news from people convinced they need to protect themselves.

    These are all great answers. Our risk does not warrant preparing in this way. A better preparation for us all is to be ready for an earthquake of similar magnitude to what we have seen in Japan and less recently in Christchurch, New Zealand.

    Most credible agencies insist it's not only a waste of time, but in fact could be more danger than it's worth. Including:

    The California Department of Health

    ("Radiation from Japan is expected to be thousands of times less than daily background radiation from natural and man-made sources—like the sun, air, soil, medical imaging, and life-saving therapies.")

    The Johns Hopkins Office of Critical Event Preparedness

    (""CEPAR experts note that harmful levels of radiation are not expected in the United States as a result of the nuclear crisis in Japan, and thus, taking the medication as a preventive measure is wholly unnecessary.")

    The Washington State Department of Health

    ("We do not advise the public to purchase KI. It’s not an “anti-radiation pill;” it’s only helpful in very specific conditions, and protects only against radioactive iodine."

    - also this big chunk -

    "KI protects the thyroid against high concentrations of radioactive iodine, which is a type of radioactive material that is very unlikely to make it to the upper atmosphere. If it were to get in to the upper atmosphere, by the time the winds blew it from Japan to other parts of the world such as Washington, it would be at such low levels that it would pose no health threat to people. Levels would be diluted by wind and distance. Potassium iodide is typically given to people who are very near the source of high levels of radioactive iodine, such as nuclear plant workers or residents near the plant who may not be able to get out of the area soon enough after a nuclear incident. In Japan, for example, the evacuation zone is within 20 kilometers, or about 12 miles, of the plant. We’re thousands of miles away. The state Department of Health recommends against KI for people in this state concerned about radiation from the Japanese nuclear event.")

    Actually this FAQ is pretty good.

    In short, no.

    No. There is no need to discuss it further.

    I've been feeding my toddler nori just to be safe. It's super high in iodine. I eat it too. I'm not sure if it would be a high enough dose in the case of emergency though.
