introduction foodstuffs are known to contain natural and artificial radionuclides. determination of radionuclide concentration is of great significance for the protection of human health. the main objective of the present study was the quantification of radionuclides in tea samples, cultivated in guilan province in north of iran. materials and methods the activity concentrations of 226ra, 232th...

background: due to the evacuation of some industrial wastewaters to arvandrood, the presence of the radionuclide material in the river is likely. the purpose of this study was to determine the radioactivity rate in arvandrood land area to the persian gulf. methods: : the concentration of cesium radionuclide (cs137) was measured in 20 sediment samples and 8 water samples which were collected fro...

AIMS Different methods exist for measuring left ventricular function echocardiographically; each may be error prone due to the abnormal pattern of ventricular activation during pacing. METHODS AND RESULTS Echocardiography was undertaken on 307 patients with permanent pacemakers; a subset of 57 underwent radionuclide ventriculography. Intrinsic and paced beats were analysed for left ventricula...

introduction artificial and natural radionuclides are found in diverse environmental compartments, such as water, soil, rocks, vegetables, animals, and human body tissues. as such, humans and environments are at constant exposure of these radiation types. in this research investigated specific activities of radionuclide and dose assessment of some species of mushrooms. materials and methods in ...

statement of problem: condylar hyperplasia of the mandible is a self limiting abnormality which can cause facial asymmetry, temporomandibular joint (tmj) dysfunction and esthetic problems. treatment planning is based on the results of isotope scanning, clinical findings and patient age. single photon emission tomography (spect) is considered to be a sensitive method in the calculation of condyl...

A radionuclide counting method, performed with the patient prone and the neck flexed, was used successfully to diagnose CSF rhinorrhea in two patients. A normal radionuclide ratio (radionuclide counts in pledget/radionuclide counts in 1-ml blood sample) was obtained in 11 normal control subjects. Significance was determined to be a ratio greater than 0.37. Use of radionuclide counting method of...

naturally occurring radionuclide of terrestrial origin (also called primordial radionuclide) are present in various degrees in all media in the environment, including the human body itself. their concentrations in environment decrease continually by decaying. the main objective of this study is to evaluate the radioactivity levels and health risks due to terrestrial radionuclide in soil of yalo...

The characteristics of lymphedema on radionuclide lymphoscintigraphy were studied, and the diagnostic value of radionuclide lymphoscintigraphy in lymphedema was evaluated. In this report radionuclide lymphoscintigraphy was performed in 110 cases of clinically suspected lymphedema. A retrospective study method was used to analyze the imaging results. The typical pattern of lymphedema on radionuc...
