Evaluation of Radiation Exposure Pattern and Radiation Absorbed Dose Resulting from Occupational Exposure of Anesthesiologists to Ionizing Radiation
Introduction: Little information is available concerning the radiation exposure of anesthesiologists, and no such data have previously been collected in Iran. This prospective study was performed to determine the amount of radiation exposure of anesthesiologists for the purpose of assessing whether or not dangerous levels of radiation exposures were being reached, and to identify factors that c...
متن کاملEstimation of radiation dose of emergency exposure during the hospitalized 131I therapy patient
Background: The aim of the study was to estimate the radiation dose during emergency exposure to patients treated with iodine-131 during the isolation period. Materials and Methods: The dose rate from a sample of 192 patients administrated by three different radioactivity of 131I (3.7, 5.55 and 7.4 GBq) was measured, at 1 meter after 1, 24 and 48 hours post dose administration, at three d...
متن کاملRadiation Hormesis
The word “hormesis” is derived from the Greek word “hormaein” meaning: “to excite,” which is the origin of the word “hormone.” In 1902, the English physiologist, E. Starling, discovered that an acid extract from the human duodenum contained a substance designated as secretin that, when discharged into the bloodstream, stimulated the pancreas to release its secretions when food has passed throug...
متن کاملLow-dose radiation induces antitumor effects and erythrocyte system hormesis.
OBJECTIVE Low dose radiation may stimulate the growth and development of animals, increase life span, enhance fertility, and downgrade the incidence of tumor occurrence.The aim of this study was to investigate the antitumor effect and hormesis in an erythrocyte system induced by low-dose radiation. METHODS Kunming strain male mice were subcutaneously implanted with S180 sarcoma cells in the r...
متن کاملMitochondrial hormesis links low-dose arsenite exposure to lifespan extension
Arsenite is one of the most toxic chemical substances known and is assumed to exert detrimental effects on viability even at lowest concentrations. By contrast and unlike higher concentrations, we here find that exposure to low-dose arsenite promotes growth of cultured mammalian cells. In the nematode C. elegans, low-dose arsenite promotes resistance against thermal and chemical stressors and e...
