Nowadys herbal medicine is marketing without standard toxicological study. Although people believe that herbal medicine do have any toxic effects, there are some reports indicating the toxicity of the herbal medicine. The aim of this investigation is to study the renal and hepatic effects of Echium Amoenum (EA) and Valeriana Officinalis (VO). Percolated extract of these plants with doses of 100...

Patients receiving diagnostic doses of radiopharmaceuticals become a source of contamination and exposure for those who come in contact with them, such as nuclear medicine technologists, relatives and nurses. Therefore, the measurement of external radiation dose from these patients is necessary. In this study, the dose rates at distances of 10, 50 and 100cm from 70 patients who received d...

The purpose of this paper is to review basic radiation biology and associated terminology to impart a better understanding of the importance of basic concepts of ionizing radiation interactions with living tissue. As health care workers in a field that utilizes ionizing radiation, nuclear medicine technologists are concerned about the possible acute and chronic effects of occupational radiation...

introduction: radioactive materials deliver internal radiation dose to patients in nuclear medicine. manual internal radiation dose assessment is a complicated method. introduction of a simple dose calculation software is the main goal of the present study. methods: using the best current data in internal dose calculation (s-factors) recommended by icrp and by considering other technical metho...

background: hot lab is a specially designed room in a nuclear medicine hospital where the radiopharmaceuticals are delivered, stored and prepared for dispensing. 99mo/99mtc-generator is the major source in the hot lab used for various medical imaging. it is important to maintain a standard for hot lab procedures to optimize the patient care and minimize radiation exposure to all nuclear medicin...
