High-dose Potassium Iodide (KI) only helps to protect the thyroid from absorbing radioactive iodine. Potassium Iodide has no impact on the uptake of other radioactive materials and provided no protection against external radiation exposure. Do not to use as a preventative. Can be harmful to people with allergies to iodine or shellfish, with certain skin disorders, renal disease, some chronic diseases or those with thyroid problems.

Do not take Potassium Iodide (KI) in high doses until instructed to by a public health official or government agency. Serious side-effects can result from high doses in the absence of a radiation emergency.
Visit the FDA website and the CDC website for more information.

06. An Alternative Mechanism for Radioprotection by Dimethyl Sulfoxide (DMSO) The radioprotective effects of dimethyl sulfoxide (DMSO) have been known for many years, and the suppression of hydroxyl (OH) radicals induced by ionizing radiation has been thought to be the main cause of this effect. The results indicated that low concentration of DMSO exerts radioprotective effects through the facilitation of DNA double-strand break repair rather than through the suppression of indirect action.

10. The Basics of Boron Neutron Capture Therapy Of the various nuclides that have high neutron capture cross-sections, Boron-10 is the most attractive. It is non radioactive and readily available, comprising approximately 20% of naturally occurring boron. Boron-10 absorbs a low energy neutron and ejects an energetic short-range alpha particle and lithium ion which deposit most of their energy within the cell containing the original boron-10 atom. Boron-10 in or adjacent to the tumor cells disintegrates after capturing a neutron and the high energy heavy charged particles produced destroy only the  cells in close proximity to it, primarily cancer cells, leaving adjacent normal cells largely unaffected.

11. Calcium Bentonite Clay and Protection from Radiation Exposure  Radioactive material is formed carrying a positive ionic charge. Calcium Bentonite Clay is a negatively charged ion. Simply put, Calcium Bentonite Clay adsorbs and absorbs, capturing positive charged ions, and you wash them off or pass them through your body. Unlike other clays, only Smectites (Bentonites) can absorb andadsorb and are characterized by its expandable properties.

Key words for internet research: potassium iodide, potassium iodide and KI, potassium iodide and radiation emergency, potassium iodide and nuclear emergency, potassium iodide and thyroid cancer, iodine for thyroid, iodine for radiation, radiation and DMSO, radiation and calcium bentonite clay, radiation and boron

Learn More About Iodine

  1. Iodine Overview by the Linus Pauling Institute

    Iodine is required by humans for the synthesis of thyroid hormones. Iodine is an essential component of the thyroid hormones, triiodothyronine (T3) and thyroxine (T4), and is therefore essential for normal thyroid function. Thyroid hormones regulate a number of physiologic processes, including growth, development, metabolism, and reproductive function. Thyroid enlargement, or goiter, is one of the earliest and most visible signs of iodine deficiency. Some foods contain substances that interfere with iodine utilization: casava, some species of millet and cruciferous vegetables (for example, cabbage, broccoli, cauliflower, and Brussels sprouts) and some soybean isoflavones.

  2. Iodine on MedLine Plus

    Chronic iodine deficiency can lead to numerous health problems in children and adults, including thyroid gland dysfunction (including goiter) and various neurologic, gastrointestinal, and skin abnormalities. Iodine deficiency in pregnant or nursing mothers can lead to significant neurocognitive deficits in their infants. "Cretinism" or severe mental retardation is a rare outcome of severe iodine deficiency during early development. Growth stunting, apathy, impaired movement, or speech/hearing problems may occur. Iodine deficiency is rare in industrialized countries such as the United States, due to the enrichment of table salt and cattle feed with iodine.


  3. Role of Thyroid Hormones

    One important function of thyroid hormone (TH) is helping the body convert food into energy and heat. TH elevates the heart rate to meet the increased oxygen needs. TH also regulates body temperature. Injury and illness lower TH levels. TH imbalance has a profound effect on cardiovascular fitness because TH helps control heart rate and blood pressure. Estrogen partially blocks the efficiency of TH, so women compensate by producing more TH than men. TH plays a major role in the development in all vertebrates. In humans, thyroid hormone plays a notable role in brain development from the middle of pregnancy to the second year of life. Hypothyroidism is the second leading cause of high cholesterol, after diet.

  4. The High Cholesterol Thyroid Connection: Undiagnosed Thyroid Disease May Be the Reason for Your High Cholesterol

    As many as ten million Americans with high cholesterol levels may not know that their cholesterol is elevated due to undiagnosed thyroid problems. Undiagnosed and undertreated hypothyroidism can cause elevated cholesterol. The Food and Drug Administration recommend thyroid testing in patients with high cholesterol levels.

  5. Perchlorate Controversy Calls for Improving Iodine Nutrition

    Perchlorate is a water pollutant that can potentially interfere with thyroid function. Perchlorate accumulates in fresh vegetables, such as lettuce, if they are irrigated with polluted water. The chemical is of concern because it amplifies thyroid problems in people who are iodine deficient. Some scientists have concluded that vegetarians, and especially vegans, can be more susceptible to thyroid problems as a result of perchlorate exposure because they may have lower iodine intakes than the general public. Impaired thyroid function is especially problematic for women who are pregnant or nursing a child.


  6. Vegans and Iodine

    North American vegans should take a modest iodine supplement; 75-150 mcg every day or every other day should be enough.


  7. Thyroid Hormones: Pregnancy and Fetal Development

    Thyroid hormones are critical for development of the fetal and neonatal brain, as well as for many other aspects of fetal growth. Hypothyroidism in either the mother or fetus frequently results in fetal disease; in humans, this includes a high incidence of mental retardation.


  8. Nonradioactive Iodide Effectively Induces Apoptosis in Genetically Modified Lung Cancer Cells

    This is the first report demonstrating that a therapeutic dose of nonradioactive iodide has potent efficacy and high selectivity against lung cancer when used in combination with genetic modification of cancer cells to express the NIS/TPOgenes


  9. Iodine for Health

    There is growing evidence that Americans would have better health and a lower incidence of cancer and fibrocystic disease of the breast if they consumed more iodine. Iodine effectively relieves signs and symptoms of fibrocystic breast disease. Iodine also induces apoptosis, programmed cell death. Its anti-cancer function may well prove to be iodine's most important extrathyroidal benefit. Iodine removes toxic chemicals — fluoride, bromide, lead, aluminum, mercury — and biological toxins, suppresses auto-immunity, strengthens the T-cell adaptive immune system, and protects against abnormal growth of bacteria in the stomach.
