  PANNA: Why EPA Should Not Register Methyl Iodide
The registrations of methyl iodide (also known as iodomethane) are as a new chemical touted as a replacement for methyl bromide for soil fumigant applications.
Methyl iodide is widely used in chemical synthesis because of its extraordinary ability to react with electron-rich molecules.
The vapor pressure of methyl iodide is 400 mm Hg, compared to 1,800 mm Hg for methyl bromide, 18 mm Hg for MITC and 29 mm Hg for 1,3-dichloropropene (Telone).

  Iodide - Wikipedia, the free encyclopedia
An iodide ion is an iodine atom with a −1 (negative one) charge.
Compounds with iodine in formal oxidation state −1 are called iodides.
This is the same naming scheme as is seen with chlorides and bromides The chemical test for an iodide compound is to acidify the aqueous compound by adding some drops of acid, to dispell any carbonate ions present, then adding lead nitrate, yielding a bright yellow precipitate of lead iodide.

 POTASSIUM IODIDE SHOULD BE AVAILABLE TO PEOPLE LIVING NEAR NUCLEAR POWER PLANTS
Potassium iodide can prevent thyroid cancer caused by exposure to radioactive iodine, a compound that could be released during a severe accident at a nuclear power plant.
Potassium iodide will not protect the body against other types of radioactive isotopes released during nuclear-reactor incidents or those likely to be used in a so-called dirty bomb, added the committee that wrote the report.
For potassium iodide to be most effective, it must be taken within a few hours before or after exposure to radioactive iodine, the report says.

Potassium iodide (KI) as a thyroid blocking agent in radiation emergencies, as an adjunct to other public health protective measures, such as evacuation, sheltering and control of contaminated foodstuffs, in the event that radioactive iodine is released into the environment.
Potassium iodide from tablets (either whole or fractions) or as fresh saturated potassium iodide solution may be diluted in milk, formula, or water and the appropriate volume administered to babies.
Lactating females should be administered potassium iodide for their own protection, as for other young adults, and potentially to reduce the radioiodine content of the breast milk, but not as a means to deliver potassium iodide to infants, who should get their potassium iodide directly.

 Welcome to The IAAM - Potassium Iodide Facts
Because of this, one dose of potassium iodide, which is not harmful to the thyroid, works by filling the gland so it cannot take up any radioactive iodine.
You can take potassium iodide, but should have medical follow-up: If you are pregnant or could be pregnant or are breastfeeding you should have one dose only, and then get medical follow-up.
In a situation where potassium iodide will be required for more than 24 hours, you will be supplied with what you need.

 When You Should Use Potassium Iodide in a Radiation Emergency ?   (Site not responding. Last check: 2007-10-19)
Potassium iodide is a salt of stable (not radioactive) iodine.
There is so much stable iodine in the potassium iodide that the thyroid gland becomes "full" and cannot absorb any more iodine—either stable or radioactive—for the next 24 hours.
Tapotassium iodide ng a higher dose of potassium iodide, or tapotassium iodide ng potassium iodide more often than recommended, does not offer more protection and can cause severe illness or death.

 Tropical cyclone - Wikipedia, the free encyclopedia
It was thought that the seeding would cause supercooled water in the outer rainbands to freeze, causing the inner eyewall to collapse and thus reducing the winds.
The project was dropped after it was discovered that eyewall replacement cycles occur naturally in strong hurricanes, casting doubt on the result of the earlier attempts.
Today it is known that silver iodide seeding is not likely to have an effect because the amount of supercooled water in the rainbands of a tropical cyclone is too low.
