The information I want to share with you concerns prevention of the effects of radioactive fallout which is possible from Japan at this time.
- Preventing Absorption of Radioactive Iodine
Getting Iodine from Supplements
I take the USANA Essentials which cover the daily dosage below(except for iron).
A good daily supplement to protect the thyroid from irradiated iodine is:
- Potassium iodide 300 mcg providing 250 mcg iodine
- Vitamin A (Retinol) 5,000 IU
- Ferrous gluconate 100 mg providing 12 mg elemental iron
- Selenomethionine 200 mcg
- Zinc gluconate 50 mg providing 5 mg elemental zinc
- One dose per day for 90 days with food.
NOTE – Potassium iodide (KI) is often given orally immediately after exposure to radiation. This helps protect the thyroid from the effects of ingesting radioactive iodine if an accident occurs at a nuclear power plant, for example.
Sheilding refers to the use of absorbent material to cover a reactor or other source of radiation, so that less radiation is emitted in the environment where humans may be exposed to it. These biological shields vary in effectiveness, depending on the material’s cross-section for scattering and absorption. The thickness (shielding strength) of the material is measured in g/cm2. Any amount of radiation that does penetrate the material falls exponentially with increasing thickness of the shield.
Taking X-ray rooms as an example, lead sheets may exist in the walls of the room containing the generator or barium sulphate may be incorporated into the plaster. The subject being X-rayed is viewed through a leaded glass screen and lead aprons are worn in cases where operators need to be in the same room as the subject.
