10 Pack iOSAT Potassium Iodide Radiation Blocking Tablets KI Survival Emergency

iOSAT  Potassium Iodide Tablets

For Thyroid Blocking in a Radiation Emergency

  • 10 Packs of 14 tablets, for a total of 140 tablets, 130 mg each.
  • During a nuclear emergency situation iOSAT protects against radioactive iodine, by preventing its absorption by the thyroid gland.
  • The only full-strength tablet for radiation blocking which is FDA approved to be legally sold in the US. Only iOSAT has passed all FDA tests for purity, quality, safety and efficacy.
  • This method of protection is extremely safe and effective, and up to 99% of all radiation induced thyroid damage can be avoided by the use of iOSAT.
  • Who needs iOSATThere are many commercial nuclear plants in the world, each with one or more reactors. It is estimated that a “Chernobyl-sized” accident could spread radioiodine for hundreds of miles around each. Many people live within the danger radius of multiple plants.
Chernobyl, 3-Mile Island, Fukushima… a nuclear reactor meltdown is not a question of if, it is a question of WHEN and WHERE. 
To be on the safe side, it’s best to have a pack of iOSAT at home if you live within 2000 km from a nuclear reactor.

iOSAT is the first “Radiation Protective” or Thyroid Blocking” agent to be sold directly to the general public. Its active ingredient, 130 mg. of potassium iodide (KI), gives virtually complete protection from the most feared consequence of a nuclear accident – a meltdown and release of radioactive iodine into the environment.

Radioactive iodine (primarily I-131) is a waste product of nuclear fission produced in reactors and bombs. Its potential impact on human health is staggering, and it could affect more people (perhaps far more people) than all other radioactive sources combined. US Nuclear Regulatory Commission (NRC) reports indicate that a major release could injure hundreds of thousands of people, and many believe that the government is underestimating the danger.

What makes I-131 so dangerous is that the body can not distinguish it from ordinary iodine. As a result, if it is accidentally swallowed (in contaminated food or water), or inhaled (it can remain in the atmosphere for days), it will be absorbed into the thyroid gland and will remain there long enough to slowly poison its victim. It can take 20 to 30 years, but eventually it can lead to cancer, thyroid damage, growth and birth defects, or death. Children, whose thyroids are especially active, are extremely susceptible to it.

But iOSAT protects against radioactive iodine by preventing its absorption by the thyroid glandiOSAT saturates (blocks) the thyroid with stable iodine, “filling it to capacity”. Once filled, the gland “turns off” its absorption mechanism, and it will remain off long enough for the radioactive iodine to disappear naturally. This method of protection is extremely safe and effective, and up to 99% of all radiation induced thyroid damage can be avoided by the use of iOSAT.

The value of potassium iodide was demonstrated following the Chernobyl nuclear accident, where authorities began mass distribution (millions of doses) of KI just hours after the explosion. In the years following the accident in areas where people received the drug, the incidence of thyroid cancer has not increased. But where KI was not distributed, previously rare forms of juvenile thyroid cancer have begun appearing at epidemic rates, with over 11,000 cases reported by the year 2000.

But the radiation did not stop at the Soviet border. In Poland, 300 miles away, authorities watched as radioactive iodine levels began climbing. Soon, authorities felt they had no choice, and doctors ordered a protective dose for every child in the country. These efforts proved successful, and there has been no increase in thyroid cancer in Poland due to Chernobyl. Similar preventative measures took place in other areas throughout Europe, with similar success.

These programs succeeded because most European countries had long stockpiled KI for emergency use in the event of a nuclear accident or war. Planners, therefore, had access to the drug (which should be taken prior to exposure for maximum effectiveness) when it was needed. Unfortunately, similar mass stockpiles are not kept in the United States.


Who needs iOSAT?

While nuclear reactors contain numerous radioactive products, most of the danger can be isolated to iodine. This is because iodine is unique in that:

1.    It is very abundant in a reactor,

2.    It remains in the environment for as long as 60 days,

3.    It is biologically active, and once absorbed stays in the body where it is concentrated in the thyroid, and

4.    Under accident conditions it can form an aerosol which can be blown downwind for hundreds of miles

No other radioactive product shares these characteristics, which is why health professionals fear the release of radioactive iodine more than any other consequence of a reactor accident. Estimates suggest that 95% of all health effects in a nuclear accident would be thyroid related, and that the prompt use of KI could prevent almost all of the injuries that would otherwise occur (in areas more than a few miles away from the plant site).

Unfortunately, current safety regulations for America’s nuclear plants are surprisingly unconcerned with the impact of iodine on the, literally, millions of people located more than a few miles from the reactor. Instead, emergency planning is essentially limited to a small “Emergency Planning Zone” (EPZ) of 5 to 10 miles around the plant, and is focused on evacuation of all people who might be exposed to radiation. There are virtually no plans in place to protect the much larger number of people located from 10 to 200 miles from the plant site, for whom evacuation is not feasible.

Yet, the potential for large casualties outside the EPZ is not unknown by authorities. According to figures provided by the US Nuclear Regulatory Commission (NRC), radioiodine could injure people located as far away as 200 miles from a reactor. If, for example, an accident were to occur at one of the Indian Point reactors (25 miles north of New York City), enough radioiodine could be released to potentially injure one person in every other household in northern New Jersey. In New York City, itself, from 25% to 40% of all adults would be expected to be injured, with children at twice the risk. At these levels, of course, casualties would number in the millions.


How safe is it?

Potassium iodide is extremely safe in the dosage provided by iOSAT. Because it is widely used in other treatments, its effects are well known. Millions of KI tablets are consumed annually in the US with virtually negligible side effects. Calculations by the National Council on Radiation Protection suggest that the incidence of adverse reactions to the KI in iOSAT can be as low as 1 in 10 million, and often no more than a mild skin rash.

Because of the inherent safety of KI, the FDA allows iOSAT to be sold without a prescription for radiation protection. Its use, however, should be limited to radiation emergencies, and only when recommended by emergency response authorities.

Proof of KI’s safety was demonstrated beyond reasonable doubt following the Chernobyl accident. As reported in The American Journal of Medicine, (Volume 94, May, 1993), despite very high levels of public anxiety caused by the fear of radiation, the incidence of side effects in Poland among the roughly 18 million who took iodine was very small. Approximately 99.8% of those who took KI had no side effects whatsoever, with only a few recipients reporting a mild skin rash or stomach upset. Only 2 cases of more serious side effects were noted, and both of these occurred among people with known allergies to iodide who had been warned not to take KI — but did so anyway.


What’s the dosage?

iOSAT should be stored in a dry, room-temperature environment, with the blister packages unopened until its use is directed by public health authorities in a radiation emergency. Then, one tablet per day should be taken for as long as directed by public health officials. Under this regimen, sufficient thyroid blocking will be achieved to insure protection even in the worst accident. Of course, anyone taking iOSAT should follow all instructions from the public health authorities, including

evacuation if conditions are judged to warrant it.


Who should not take iOSAT?

The only people who should not take iOSAT are people with a specific allergy to iodide. Pregnant and nursing women, as well as infants, may take the drug. Parents should be aware that children and unborn are extremely susceptible to radioiodine poisoning. People taking other thyroid medicines may also take iOSAT.

Why iOSAT?

Only iOSAT

6.    iOSAT [potassium iodide] offers unit dose packaging for maximum shelf-life and allows for individual tablet distribution without fear of loss of packaging integrity.


The case for radiation protection

iOSAT is the first radiation protective tablet available to the general public. Experts agree that its prompt use would be the most effective measure available to protect millions of people who would be at risk in a nuclear accident or under a radiation threat from a terrorist nuclear weapon. These FDA approved tablets contain potassium iodide (KI) which provides virtually complete protection from radioactive iodine [ RAI ], the contaminant that causetranss thyroid cancer. Should RAI ever escape, the health effects would be disastrous.

It has already happened. RAI released from the 1986 Chernobyl nuclear accident spread throughout Europe for hundreds of miles. According to the United Nations International Thyroid Project, this led to over 11,000 cases of children’s thyroid cancer by the year 2000, with more expected to occur before the disease peaks in about 2010.

But investigators, including the UN, the World Health Organization (WHO), the US FDA, the US Nuclear Regulatory Commission (NRC) and The American Thyroid Association, uncovered the following unexpected findings at Chernobyl:

1.     Thyroid cancer was the only prominent health problem to effect the general population. Although the accident released many types of radioactive isotopes to the environment, all of the injuries (to people located more than a few miles from the reactor) were limited to just the effects of radioactive iodine. As the NRC and WHO have reported,

“except for thyroid cancer, there has been no confirmed increase in the rates of other cancers, including leukemia … attributed to releases from the accident. In addition, there is no evidence of any excess hereditary disease in children born after the accident.”

In other words, the use of iOSAT can safeguard people from most of the danger of a nuclear accident.

2.     The accident was not local. Within five years of the accident, children’s thyroid cancer began appearing throughout Europe. According to the NRC,

“the vast majority of the cancers were diagnosed among those living more than 50 km (31 miles) from the site.”

Others reported identical findings, with the WHO noting,

“the increase has been documented up to 500 km from the accident site, [and that] significant doses can occur hundreds of kilometers beyond emergency planning zones.”

At the time of the Chernobyl accident, Soviet authorities immediately distributed large amounts of potassium iodide to people living within 30 miles around the plant in order to neutralize the radiation. This protection was effective. As shown below, only 3% of the first 750 recorded cancers took place near the Chernobyl reactor. But farther away (beyond 30 miles) almost no KI was available, and children in these areas suffered dramatically. Without KI, children’s cancer rates soared, with the vast majority (as high as 97%) of the cancer taking place more than 30 miles from the reactor. Perhaps most disturbing was that 17% of the early cancer occurred more than 350 km (200 miles) distant. In Poland, the government distributed previously stockpiled KI to nearly every child, with the result that Poland, alone among the countries in the area, suffered no cancer due to Chernobyl.

As can be seen, in a serious accident, people hundreds of miles downwind of the site may require for radiation protection. This fact raises serious questions about the feasibility of the government’s current emergency planning strategy, which is based on the evacuation of anyone at risk. Millions of people might have to be relocated, and how this could be achieved is not clear. Worse, while trying to evacuate, people could be caught outdoors, sitting in traffic, where they would be highly vulnerable

to RAI exposure and totally unprotected.
