objective(s): the aim of this study was to determine whether high-dose radioactive iodine (na131i) outpatient treatment of patients with thyroid carcinoma is a pragmatically safe approach, particularly for the safety of caregivers. methods: a total of 79 patients completed the radiation-safety questionnaires prior to receiving high-dose radioactive iodine treatment. the questionnaire studied th...
the present nuclear leakage crisis from japan is a topic to be discussed in present public health. in radiology, the leaked radioactive elements are considered hazard. here, the author briefly reviews and discusses on two important radio-hazard elements in post nuclear power plant crisis, radioactive iodine and radioactive cesium. based on previous similar nuclear crisis in russia, it is eviden...

Mucus flow rates were measured in the intact trachea of anaesthetized dogs, using a radioactive tracer technique. Measurements were made before intubation, and after intubation at inspired air temperatures of 32, 37 and 42°C, with a constant inspired water vapour content of 33 mg/1.; and again at each temperature with a relative humidity of 75%. No significant difference in mucus flow rate was ...
All building materials contain various amounts of natural radioactive nuclides. Materials derived from rock and soil contain mainly natural radionuclides of the uranium (238U) and thorium (232Th) series, and the radioactive isotope of potassium (40K). Radiation exposure due to building materials can be divided into external and internal exposure. The external exposure is caused by direct gamma ...
Background: The Ural region is highlighted among other Russian regions for its unfavorable radiation situation and complexity of the overall environmental situation. The source of man-made radioactive contamination is the work of the "Mayak" Production Association. A significant radioactive contamination has happened as a result of several radiation incidents in the early period ...
Extended Abstract Introduction and Purpose: In the present study, the effects of radiation from radioactive waste in an obsolete uranium mine on the change in the quantity and quality of the metabolic content in the essential oil of Artemisia absinthium were investigated. Material and Methods: In order to have full access to the radiation exposure information of the study areas, a point-to-p...
Environmental sources of radioactive materials and their relation to lung doses and lung burdens are described. The approaches used and the problems encountered in estimating lung doses are illustrated. Exposure to radon daughter products is contrasted to exposure to plutonium as particular examples of the hazards associated with radioactive materials of different chemical and physical characte...
