PACOM officials direct distribution of potassium iodide tablets Published March 25, 2011 By Staff Sgt. J.G. Buzanowski 374th Airlift Wing Public Affairs YOKOTA AIR BASE, Japan (AFNS) -- As a precautionary measure, U.S. Pacific Command officials directed distribution of potassium iodide tablets March 22 here. Base officials, however, are stressing there is no indication of increased exposure here. "We want everyone who may need the pills to be prepared, whether it's because of potential mission-related hazards or an unforeseen change in circumstances," said Col. Otto Feather, the 374th Airlift Wing commander. "At this point, there is no reason for people on or near Yokota Air Base to be concerned. This decision is purely precautionary, and while there is no indication of increased exposure, distributing the tablets now means people have them in case they need them later." No one should take the tablets at this time, and no one should take the tablets in the future unless advised to do so by U.S. authorities, officials said. The tablets work by flooding receptors in the thyroid gland with iodine so the body doesn't absorb overwhelming amounts of irradiated iodine in the event of exposure, said Capt. (Dr.) Robert Ochsner, an urgent care physician at the 374th Medical Group. Irradiated iodine can cause nausea, vomiting and other issues. "There is currently no need for anyone at Yokota (Air Base) to begin taking the tablets," Doctor Ochsner said. "While KI is safe, it can be harmful to take them incorrectly, and they should only be taken once in a 24-hour period and only then after base leadership has determined it's necessary." "KI" is the chemical abbreviation for potassium iodide. Experts test the air here hourly to ensure dangerous amounts of radiation aren't present, the captain said. While small, trace amounts of radiation are normal and readily present anyway, there is no danger at this time. "There are cities in the U.S. that have higher levels of radiation than Yokota (Air Base) does right now," Dr. Ochsner said. Because of the failed cooling system at a nuclear power plant near Fukushima, Japan, roughly 130 miles north of Yokota AB, there have been increased levels of radiation in areas near the power plant, officials said. Aircrew members and select others have received KI tablets if a mission might take them close to areas with elevated radiation levels. "It's our responsibility to take all precautionary measures available to ensure the safety of our servicemembers, families and other personnel who work at Yokota (Air Base)," Colonel Feather said. The tablets are available for pick-up through the medical group for servicemembers and their dependents, officials said. Instructions are included with the packets. Officials ask that one representative more than 18 years old pick up packets for their entire household to minimize traffic at the distribution area. A form is required to be filled out before a family representative will be given the KI tablets. The form is available for download here.
