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 美國出現個人中毒案例


【台灣醒報╱記者莊瑞萌╱台北報導】 2011.03.18 01:26 pm


　　美國民眾擔心日本輻射可能飄向美國，部分地區已經出現民眾購買碘片甚至囤積的風潮，同時也傳出有民眾因自行服用，結果造成身體出現不適症狀，美國毒物管製中心表示，全美已出現57起，因服用碘片而造成中毒的案例。
　　雖然目前美國國內並未偵測到任何輻射塵威脅，不過，卻已出現民眾自行服用碘片以為可以預防輻射，目前「美國毒物管製中心協會」（American Association of Poison Control Centers）已接獲57起，民眾因自行服用碘片而中毒的案例，其中至少7人出現嘔吐、心悸與暈眩等症狀。
　　另外，根據美國科學工作者關懷聯盟對外表示，目前居住在美國地區的民眾此時實在「不必要」服用碘片，早在周三，美國衛生部曾發表聲明稿指出，「美國衛生部並未呼籲民眾應購買碘片作為預防，同時，若對於輻射塵後續發展有任何疑慮的民眾，應該隨時聽從來自衛生部門的指示。」
　　目前美國環保署為了讓民眾放心，除原有加州12座監控輻射量儀器外，另外還投入了40部移動式輻射偵測器，包括在夏威夷、關島與阿拉斯加州也都將設置，另外，加州洛杉磯郡公共衛生部部長費爾定（Jonathan E.Fielding）表示，「呼籲民眾非必要時，千萬不要服用碘片，」他也提醒，部分服用民眾可能出現過敏、惡心或皮膚紅腫現象。
　　根據美國疾病管製局表示，碘化鉀或稱碘片，當發生輻射汙染時，可以避免身體吸收過多輻射碘導致體內甲狀腺被破壞。
