Patient dose in routine X-ray examinations in Yazd state
Background: Medical x-rays are the largest man-made source of public exposure to ionizing radiation. It is important to avoid conditions where the amount of radiation used is more than that needed for the procedure. Materials and Methods: The Entrance Skin Exposure (ESE) measurement was conducted for quality control of x-ray machines and survey of operator’s experimental techniques. The ESEs we...

متن کاملDose estimation with the calibration of dose-response curve of micronucleus in human peripheral lymphocytes induced by 50MeV proton beams
Background: The purpose of this paper is to establish an easy and reliable biodosimeter protocol to evaluate the biological effects of proton beams. Materials and Methods: Human peripheral blood lymphocytes were irradiated using proton beams (LET: 34.6 keV μm−1), and the chromosome aberrations induced were analyzed using cytokinesis-blocked (CB) micronucleus (MN) assay. To determine th...
متن کاملPatient effective dose evaluation for chest X-ray examination in three digital radiography centers
Background: The radiation doses resulting from diagnostic X-ray examinations are routinely measured in terms of entrance surface dose (ESD) and effective dose (ED). In this study, for the purpose of radiation protection, the radiation doses received from Digital chest X-ray examination were evaluated in terms of ESD and ED. Material and Methods: The ED was calculated by using the MCNP ...
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...
