CONTEXT Substantial uncertainty persists about the indications for radioactive iodine for thyroid cancer. Use of radioactive iodine over time and the correlates of its use remain unknown. OBJECTIVE To determine practice patterns, the degree to which hospitals vary in their use of radioactive iodine, and factors that contribute to this variation. DESIGN, SETTING, AND PATIENTS Time trend anal...

The Fukushima Daiichi Nuclear Power Plant accident released large amounts of radioactive substances into the environment and contaminated the soil of Tohoku and Kanto districts in Japan. Removal of radioactive material from the environment is an urgent problem, and soil purification using plants is being considered. In this study, we investigated the ability of 12 seed plant species and a cyano...

The safety and security risk posed by highly radioactive, long-lived sources at the end of their normal use has not been consistently well-managed in previous decades. The Brazilian Cs-137 accident in 1986 and the Thailand Co-60 accident in 2000 are prime examples of the consequences that ensue from the loss of control of highly dangerous sources after their normal use. With the new internation...

INTRODUCTION Primary standards of radioactivity are in some ways, analogous to fixed points in the temperature scale in that each can be used for comparison with "unknowns" not too far removed from the standard. Over a thousand radioactive species are known to exist, but only a comparatively few satisfy such basic requirements for primary standards as: known decay scheme; appropriate half life ...

membrane assisted liquid extraction(male) technologies are gaining an important role as an extraction /separation technique for actinides and are being deployed as a  promising tool for remediation of nuclear waste generated in the reprocessing plant and other radioactive wastes containing a trace level of radionuclides. the present contribution outlines the classification of membrane assisted ...

BACKGROUND Ablative radioiodine-131 ((131)I) therapy is used in the standart treatment procedure of thyroid carcinoma and procedures using (131)I represent the majority of Nuclear Medicine therapeutic procedures. The principal route of (131)I excretion after the administration of (131)I is the urine. Amifostine is an organic thiophosphate ester prodrug and the kidney concentrations of the activ...

Background: Poorly educated people in some parts of Iran use burned mantles as a wound healing medicine. Materials and Methods: To perform surface area measurement, twenty rats were divided randomly into two groups of 10 animals each. The first group received topical burned radioactive lantern mantle powder on the first to third days after making excision wounds. The second group rece...
