Introduction: Nuclear accidents release large quantities of radioactive materials into the environment. Iodine-131 and cesium-137 are two radionuclides released during nuclear accident, which can pose the greatest cancer risks. These radionuclides can be moved to other areas through rain and wind. The aim of this study was to develop efficient and economical biological...

of cancer with the hope of developing useful diag nostic and therapeutics agents. The aim in such investigations has been to find a dye which, in the intact animal, stains living tumor cells without staining surrounding tissue. A large number of acid dyes, especially in the azo series, has been rather intensively investigated for such a purpose. From these investigations there has resulted gen ...

Brown algal kelp species are the most efficient iodine accumulators among all living systems, with an average content of 1.0% of dry weight in Laminaria digitata, representing a ca. 30,000-fold accumulation of this element from seawater. Like other marine macroalgae, kelps are known to emit volatile short-lived organo-iodines, and molecular iodine which are believed to be a main vector of the i...

Rats made hypothyroid by administration of radioactive iodine and age-matched controls were individually caged and offered a choice between either water or varying concentraions of sweet (sucrose), bitter (quinine sulfate), salty (NaCl) or sour HCl solutions to drink ad libitum for 48 h periods. Comparative measurements were made of the volume of test solution consumed to that of total volume c...

After the Chernobyl accident of 26 April, 1986, population dose assessment favours the view that the radiation risk of population effected by the early fallout would be different from that in regions contaminated later. Taking into account the short half-time of the most important radioactive iodine isotopes, thyroid disorders would be expected mainly to follow the early fallout distribution. A...

OBJECTIVE The aim of the present study was to evaluate the outcome of radioiodine treatment in thyrotoxicosis in childhood and adolescence. METHODS This was a retrospective study of 27 patients (ages 7.2- 19.8 years) with a diagnosis of thyrotoxicosis who received iodine-131 (I-131) treatment from January 2007 to December 2011 in the Nuclear Medicine Division, Department of Radiology, Faculty...

INTRODUCTION Recombinant human thyroid-stimulating hormone(rhTSH) increases radioactive iodine uptake(RAIU) in selected populations, while lithium is used as an adjunct to radioactive iodine (RAI) therapy in Graves' disease with low RAIU. In this report, both drugs used in combination, overcame low iodine-131 uptake in a Graves' patient. CLINICAL CASE A 39-year old female with Graves' disease...

We describe acute myopathy following I-131 treatment for hyperthyroidism due to Graves Disease (GD) in an adolescent. A 15 year-old diagnosed with GD required treatment with radioactive iodine (I-131) therapy. Six weeks post I-131, he developed generalized muscle cramps. The CK was 19.800 U/L, the total thyroxine was 2.3 mcg/dL (29.6 nmol/L SI) and the estimated free thyroxine (EFT) was 0.5 ng/...

Graves' disease is a common cause of hyperthyroidism. Treatment options for Graves' disease include antithyroid medication, surgery or radioactive iodine (I-31) or RAI. This review will focus on the approach to RAI therapy; discussing dose selection, patient preparation, and consideration before and after administering RAI, examining aspects of pre-treatment with antithyroid medication as well ...

Iodine oxide aerosol are formed during a nuclear severe accident in the containment due to oxidation of volatile iodine either molecular or organic iodide. These oxides may exist under different chemical forms more less stable (I 2 O 4 , I 9 and 5 ). Decomposition rate has be experimentally studied better estimate cycle thus source term. aerosols decompose radiation, whatever surface deposition...
