The effect of γ-radiation dosage on the thermal stability cross-linked acrylic polymer "Carbomer-140" (СRB) was investigated. DTA, TGA, and DTG curves show multistage processes occurring in different temperature ranges heating CRB from 25 °C to 500 °C. rates decomposition were determined 40–110 °C, 180–260 260–330 330–500 In combination with results electronic structure calculations, potential ...

introduction this study was conducted to evaluate the radiographers’ awareness of radiation protection principles in the radiology centers of the hospitals of bandar abbas, iran. materials and methods this analytical cross-sectional study was conducted on 50 radiographers of three hospitals affiliated with hormozgan university of medical sciences in 2015. the data were collected using a two-par...

background: although ionizing radiation is very important in diagnostic and treatment of many diseases, the hazards of this radiation are considerable and irrefutable. one of the main stages in radiation protection is knowledge about radiation dose in radiological investigation. the aim of this study was to determine the physicians' knowledge in radiological examinations. materials and methods:...

background: the number of interventional cardiology procedures performed has increased rapidly over the past years. while these procedures help physicians avoid using highly complicated invasive methods, it usually leads to high levels of exposure to ionizing radiation of both patients and cardiologist. the dose received by the cardiologist during interventional cardiology procedures is determi...

conclusions the state of observed radiation protection principles was relatively in the weak level in the studied radiology departments especially in facilities such as ventilation system, radiography entrance, and darkroom situation. more important reason was usage changing of sections as radiology billet from related organizations. results the mean of radiation protection in the studied radio...

PURPOSE To determine whole body and hand radiation exposure to the hand surgeon wearing a lead apron during routine intraoperative use of the mini C-arm fluoroscope. METHODS Four surgeons (3 hand attending surgeons and 1 hand fellow) monitored their radiation exposure for a total of 200 consecutive cases (50 cases per surgeon) requiring mini C-arm fluoroscopy. Each surgeon measured radiation ...

A comprehensive review isn preparation of a diverse class of electromagnetic radiation processes, which may occur in atomic systems, crystal lattices, and e ergetic lectron beams interacting with uniform or pe iodic electric and magnetic fields. We present an i troduction to his review, in the form of a survey of various fundamental electromagnetic radiation processes, from both the classical a...

  The effect of gamma radiation (1, 3 and 5 kGy) on microbial quality of farmed rainbow trout (Oncorhynchus mykiss) fillets which were stored under frozen conditions (-20° C) was studied by measuring microbiological changes in 5 months. Gamma irradiation and increasing of frozen storage time had significant effects (P < /i>
