Radiation Risks To Health: A Joint Statement From Leading Scientific Experts
The growing concern surrounding the release of radiation from an earthquake and tsunami-stricken nuclear complex in Japan has raised fears of radiation exposure to populations in North America from the potential plume of radioactivity crossing the Pacific Ocean. To help Americans understand their radiation-related health risks, the American Association of Clinical Endocrinologists (AACE), the American Thyroid Association (ATA), The Endocrine Society and the Society of Nuclear Medicine (SNM) issued a joint statement (http://www.endo-society.org/advocacy/policy/upload/Joint-Statement-on-Radiation-Risks-to-Health.pdf).
The statement suggests that the principal radiation source of concern, in regard to impact on health, is radioactive iodine including iodine-131.This presents a special risk to health because exposure of the thyroid to high levels may lead to development of thyroid nodules and thyroid cancer years later.
The statement discourages individuals needlessly purchasing or hoarding of KI in the United States. Since there is not a radiation emergency in the United States or its territories, the statement does not support the ingestion of KI prophylaxis at this time. KI can cause allergic reactions, skin rashes, salivary gland inflammation, hyperthyroidism or hypothyroidism in a small percentage of people.
AACE, ATA, The Endocrine Society and SNM will continue to monitor potential risks to health from this accident and will issue amended advisories as warranted.
