tailieunhanh - PROTECTION OF THE THYROID GLAND IN THE EVENT OF RELEASES OF RADIOIODINE

Over the past two decades the NCRP has carried out several studies and issued two reports on problems associated with a possible nuclear attack on this country. In each of these reports, any questions centering primarily about a nuclear reactor accident were avoided. The Council noted, however, the increasing interest in the potential of protective actions for alleviating some of the effects of the release of radioactive materials that might ensue in the event of a reactor accident. | NCRP REPORT No. 55 PROTECTION OF THE THYROID GLAND IN THE EVENT OF RELEASES OF RADIOIODINE Recommendations of the NATIONAL COUNCIL ON RADIATION PROTECTION AND MEASUREMENTS Issued August 1 1977 First Reprinting March 31 1991 National Council on Radiation Protection and Measurements 7910 WOODMONT AVENUE BETHESDA MD 20814 Copyright National Council on Radiation Protection and Measurements 1977 All rights reserved.

In each of these reports any questions centering primarily about a nuclear reactor accident were avoided. The Council noted however the increasing interest in the potential of protective actions for alleviating some of the effects of the release of radioactive materials that might ensue in the event of a reactor accident. Protective actions relating to the release of radioactive iodine had received considerable attention. One of the proposals frequently mentioned calls for the administration of natural iodine in a form which would quickly enter the blood system and be taken up by the thyroid gland thus blocking the admission of radioactive iodine. This report deals with the overall question of the uptake of radioactive iodine by the thyroid gland and the radiobiological effects resulting from the uptake and with considerations that would have to be instituted to establish an effective prophylactic program. The report is intended to be informative in nature and does not attempt to suggest .
