RADIATION RISKS TO HEALTH
A Joint Statement from the American Association of Clinical Endocrinologists
, the American Thyroid Association, The Endocrine Society, and the Society
of Nuclear Medicine
March 18, 2011
The recent nuclear reactor accident in Japan due to the earthquake and
tsunami has raised fears of radiation exposure to populations in North
America from the potential plume of radioactivity crossing the Pacific Ocean
. The principal radiation source of concern is radioactive iodine including
iodine-131, a radioactive isotope that presents a special risk to health
because iodine is concentrated in the thyroid gland and exposure of the
thyroid to high levels of radioactive iodine may lead to development of
thyroid nodules and thyroid cancer years later. During the Chernobyl
nuclear plant accident in 1986, people in the surrounding region were
exposed to radioactive iodine principally from intake of food and milk from
contaminated farmlands. As demonstrated by the Chernobyl experience,
pregnant women, fetuses, infants and children are at the highest risk for
developing thyroid cancer whereas adults over age 20 are at negligible risk.
Radioiodine uptake by the thyroid can be blocked by taking potassium iodide
(KI) pills or solution, most importantly in these sensitive populations.
However, KI should not be taken in the absence of a clear risk of exposure
to a potentially dangerous level of radioactive iodine because potassium
iodide can cause allergic reactions, skin rashes, salivary gland
inflammation, hyperthyroidism or hypothyroidism in a small percentage of
people. Since radioactive iodine decays rapidly, current estimates indicate
there will not be a hazardous level of radiation reaching the United States
from this accident. When an exposure does warrant KI to be taken, it should
be taken as directed by physicians or public health authorities until the
risk for significant exposure to radioactive iodine dissipates, but probably
for no more than 1-2 weeks. With radiation accidents, the greatest risk is
to populations close to the radiation source. While some radiation may be
detected in the United States and its territories in the Pacific as a result
of this accident, current estimates indicate that radiation amounts will be
little above baseline atmospheric levels and will not be harmful to the
thyroid gland or general health.
We discourage individuals needlessly purchasing or hoarding of KI in the
United States. Moreover, since there is not a radiation emergency in the
United States or its territories, we do not support the ingestion of KI
prophylaxis at this time. Our professional societies will continue to
monitor potential risks to health from this accident and will issue amended
advisories as warranted.

擅自服用碘片 美国出现个人中毒案例
【台湾醒报╱记者庄瑞萌╱台北报导】 2011.03.18 01:26 pm
美国民众担心日本辐射可能飘向美国，部分地区已经出现民众购买碘片甚至囤积的风潮，同时也传出有民众因自行服用，结果造成身体出现不适症状，美国毒物管制中心表示，全美已出现57起，因服用碘片而造成中毒的案例。
虽然目前美国国内并未侦测到任何辐射尘威胁，不过，却已出现民众自行服用碘片以为可以预防辐射，目前「美国毒物管制中心协会」（American Association of Poison Control Centers）已接获57起，民众因自行服用碘片而中毒的案例，其中至少7人出现呕吐、心悸与晕眩等症状。
另外，根据美国科学工作者关怀联盟对外表示，目前居住在美国地区的民众此时实在「不必要」服用碘片，早在周三，美国卫生部曾发表声明稿指出，「美国卫生部并未呼吁民众应购买碘片作为预防，同时，若对于辐射尘后续发展有任何疑虑的民众，应该随时听从来自卫生部门的指示。」
目前美国环保署为了让民众放心，除原有加州12座监控辐射量仪器外，另外还投入了40部移动式辐射侦测器，包括在夏威夷、关岛与阿拉斯加州也都将设置，另外，加州洛杉矶郡公共卫生部部长费尔定（Jonathan E.Fielding）表示，「呼吁民众非必要时，千万不要服用碘片，」他也提醒，部分服用民众可能出现过敏、恶心或皮肤红肿现象。
根据美国疾病管制局表示，碘化钾或称碘片，当发生辐射污染时，可以避免身体吸收过多辐射碘导致体内甲状腺被破坏。
