چکیده
odine-131 (131I) has been known as a radionuclide with potential adverse health effects following both occupational and environmental exposures (NCRP 1985, Zanzonico and Becker 2000, Astakhova et al. 1998). 131I has a physical half life of 8 days, biological half life of 80 days, conceptually an effective half life of 7.3 days. With respect to occupational exposures to 131I, there are two categories of workers who are potentially exposed to significant intake of this radionuclide in the course of their activity. The first groups are those working in laboratories producing 131Iradiopharmaceuticals. About one TBq per month (40 Curies) of 131I is usually handled in such laboratories. Although ABSTRACT

Monitoring of iodine-125 and iodine-131 in thyroid of individuals in nuclear medicine centers of North West provinces of Iran
Background: Due to volatility of radioactive iodine solutions, usually internal exposure would occur in personnel that are working in nuclear medicine centers. The activities in the thyroid of individual s who work in nuclear medicine centers of North West provinces of Iran were measured using NaI (Sodium Iodide) detectors. In every center, nearly 40 - 500 mCi of 131 I and 50 - 600 μ Ci of 125 ...

In research institute for nuclear medicine (Tehran University of Medical Sciences) 50 patients with follicular thyroid carcinoma were evaluted retrospectively. The purpose of the study was assesment of the response of iodine-131 therapy. The best result were achieved when the patient treated with iodine-131 for the first time, in the 4th decade of life, with total thyroidectomy and no met...

Introduction: There is a limited number of case reports published in the past decade confirming the radio-iodine presence in the tear. These observations as well as reported cases of salivary and lacrimal gland dysfunction after radioiodine therapy stimulated investigators to clarify whether lacrimal gland function can be affected post-radioiodine therapy. Hence we ...
متن کاملPersonnel internal radiation exposure to iodine-125 in a radioiodination laboratory: Exposure levels and trends
ABSTRACT Background: Monitoring internal exposure of individuals handling significant amounts of iodine-125 (I-125) for iodination is of great importance. These individuals are potentially exposed to external contamination, and internal contamination through inhalation, ingestion and intact skin absorption, to I-125. Considering radiological toxicity of this radionuclide its monitoring in the w...
