Historical use and analysis
Following the Chernobyl nuclear reactor disaster in April, 1986, a saturated
solution of potassium iodide (SSKI) was administered to 10.5 million
children and 7 million adults in Poland[26] as a prophylactic measure
against
accumulation of radioactive iodine-131 in the thyroid gland. People in the
areas immediately surrounding Chernobyl itself, however, were not given the
supplement.[27]
Potassium iodide’s (KI) value as a radiation protective (thyroid blocking)
agent was demonstrated at the time of the Chernobyl nuclear accident when
Soviet authorities distributed it in a 30 km zone around the plant. The
purpose was to protect residents from radioactive iodine, a highly
carcinogenic material found in nuclear reactors which had been released by
the damaged reactor. Only a limited amount of KI was available, but those
who received it were protected. Later, the US Nuclear Regulatory Commission
(NRC
) reported, “thousands of measurements of I-131 (radioactive iodine)
activity...suggest that the observed levels were lower than would have been
expected had this prophylactic measure not been taken. The use of KI...was
credited with permissible iodine content in 97% of the evacuees tested.”[28]
Poland, 300 miles from Chernobyl, also distributed KI to protect its
population. Approximately 18 million doses were distributed, with follow-up
studies showing no known thyroid cancer among KI recipients.[29] With the
passage of time, people living in irradiated areas where KI was not
available have developed thyroid cancer at epidemic levels, which is why the
US Food and Drug Administration (FDA) reported “The data clearly
demonstrate the
risks of thyroid radiation...KI can be used [to] provide safe and effective
protection against thyroid cancer caused by irradiation.[30]
Chernobyl also demonstrated that the need to protect the thyroid from
radiation was greater than expected. Within ten years of the accident, it
became clear that thyroid damage caused by released radioactive iodine was
virtually the only adverse health effect that could be measured. As reported
by the NRC, studies after the accident showed that “As of 1996, except for
thyroid cancer, there has been no confirmed increase in the rates of other
cancers, including leukemia, among the...public, that have been attributed
to releases from the accident.”[31]
But equally important to the question of KI is the fact that radiation
releases are not “local” events. Researchers at the World Health
Organization accurately located and counted the cancer victims from
Chernobyl and were startled to find that “the increase in incidence [of
thyroid cancer] has been documented up to 500 km from the accident site...
significant doses from radioactive iodine can occur hundreds of kilometers
from the site, beyond emergency planning zones."[25] Consequently, far more
people than anticipated were affected by the radiation, which caused the
United Nations
to report in 2002 that “The number of people with thyroid cancer...has
exceeded expectations. Over 11,000 cases have already been reported.”[32]
These findings were consistent with studies of the effects of previous
radiation releases. In 1945, millions of Japanese were exposed to radiation
from nuclear weapons, and the effects can still be measured. Today, nearly
half (44.8%) the survivors of Nagasaki studied have identifiable thyroid
disease, with the American Medical Association reporting “it is remarkable
that a biological effect from a single brief environmental exposure nearly
60 years in the past is still present and can be detected.”[33] This, as
well
as the development of thyroid cancer among residents in the North Pacific
from radioactive fallout following the United States' nuclear weapons
testing in the 1950s (on islands nearly 200 miles downwind of the tests)
were
instrumental in the decision by the FDA in 1978 to issue a request for the
availability of KI for thyroid protection in the event of a release from a
commercial nuclear power plant or weapons-related nuclear incident. Noting
that KI’s effectiveness was “virtually complete” and finding that iodine
in the form of potassium iodide (KI) was substantially superior to other
forms including iodate (KIO3) in terms of safety, effectiveness, lack of
side effects, and speed of onset, the FDA invited manufacturers to submit
applications to produce and market KI.[34]
Today, three companies (Anbex, Inc., Fleming Co, and Recip of Sweden) have
met the strict FDA requirements for manufacturing and testing of KI, and
they offer products (IOSAT, ThyroShield, and Thyro-Safe, respectively) which
are available for purchase. The Swedish manufacturing facility for
Thyrosafe, a
potassium iodide tablet for thyroid protection from radiation manufactured
by Recipharm AB, was mentioned on the secret US 2008 Critical Foreign
Dependencies Initiative leaked by Wikileaks in 2010.[35]

"Blockage of thyroidal uptake of radioactive isotopes of iodine (e.g.,I131)
that may be accidentally released into the environment (e.g., from a nuclear
power plant), thus minimizing the risk of radiation-induced thyroid
neoplasms. Has no impact on uptake of
other radioactive materials and does not provide protection against external
irradiation of any kind."
