In the event of a nuclear accident, radioactive iodine could be released into the air and absorbed by the thyroid, damaging it and potentially killing you. This deadly chemical from nuclear warfare can remain in the air for several days, so it's best to be prepared. IOSAT is a small tablet that contains potassium iodide(a safe preventative counter-reactor to iodine). When Potassium Iodide is taken, it floods the thyroid with a stabilized iodine, preventing 99% percent of the damage caused by radioactive nuclear fallout, such as thyroid cancer and other complications. IOSAT is safe for all members of your family to take in a radiation emergency-even your dog or cat! It should be taken 30 minutes prior to exposure, and only when public health officials tell you. Defense experts recommend keeping a supply on hand for each family member, considering deadly radioactive chemicals can remain in the air for several days. The recommended dosage is as follows: Adults and children 1 year of age or older: One (1) tablet once a day. Babies under 1 year of age: One-half (1/2) tablet once a day. Crush for infants and small children. For dogs 25-30 lbs, one-quarter (1/4) tablet once a day. A 10 lb dog/cat would take 1/8 tablet daily. Crush and put it in their food, and be sure to consult with your Veterinarian to be sure your pet hasno allergies or problems with potassium. It is easy to think that this kind of emergency could never happen here, but we must be prepared for all disasters, and IOSAT is a simple, inexpensive way to protect your family in a radiation emergency. As a final note, beware of unapproved potassium iodide and iodate illegally sold for emergencies.
