Introduction: The introduction of digital radiography has led to a significant problem in terms of dose creep. To address this problem, manufacturers have established a set of exposure indicators (EI) as a feedback mechanism to safeguard against overexposure. The EI is the measure of incident exposure to the detector that is directly proportional to the signal-to-noise...

background: ionizing radiation is present in all environment of the earth’s surface, beneath the earth and in the atmosphere. human beings are exposed to external radiation from their surroundings naturally and also to internal radiation from food, water and air they consume. then, it is important to measure and develop knowledge about radiation. objective: this study is designed to evaluate th...

This study intended to optimize the radiation doses for gastroenterologists and patients during therapeutic endoscopic retrograde cholangiopancreatography (ERCP) and to compare the doses based on available data obtained by other researchers. A total of 153 patients were studied in two Gastroenterology Departments, (group A, 111; group B, 42). Thermoluminescent dosimeters (TLD) were used to meas...

Radiations and radioisotopes are used in agricultural research to induce genetic variability in crop plants to develop improved varieties, to manage insect pests, monitor fate and persistence of pesticides, to study fertilizer use efficiency and plant micronutrient uptake and also to preserve agricultural produce. Use of radiation and radioisotopes in agriculture is one of the most important fi...

Background and Objectives: Mental and physical safety is one of the most important needs of human beings, and the administrators of each community should specifically care about it. Meanwhile, hospitals, which themselves are health care providers, are in no way an exception to this rule. Thus, hospital administrators are expected to take the issues related to physical and mental safety of staff...

The Radiation Hazards Control (RHC) Section of the Radiation Safety Systems Division (RSSD) provides safety coverage on radiological aspects to various plants and facilities of BARC and other DAE units. The Division extends its expertise in dealing with safety matters pertaining to design, commissioning and operation of nuclear facilities. This report briefly summarizes the routine and the majo...
