Background: To evaluate the risk involved, there is need to know the quantum of personnel exposures in whole service. Dose reports from an Oncology Centre over 7 block periods, 5 years each from 1979 till 2013 are analyzed. Materials and Methods: Personnel monitoring (PM) reports till 1990s with film badges and later thermoluminescent (TL) badges (CaSo4.Dy) were evaluated. 35 years total servic...

Radiation exposure dosimetry for the personnel is based on measurements of phantom studies. To determine effective dose values for different X-ray equipment, TLD-measurements were performed using an Alderson Phantom in the patient position and a second phantom in the typical position of the personnel. Various types of protective clothing as well as fixed shields were considered in the calculati...

Introduction: Background radiation is originated from environmental radioactive sources cosmicandterrestrial.Materials distribution onsurface of the earth and height from sea level are not the same at various points.Absorbed dose caused by them were different at various points.In this research, Background radiation level inoutdoor different areas of Ilam province was measured and effective dose...

Introduction: One of the sources of natural occurring radiation was soils. The purpose of article was to determine soil pollution by radiation absorbed dose rate, radium equivalent activity, external hazard index, annual gonad dose equivalent and annual effective dose equivalent. Methods & Materials: The soil samples was located in Chahbahar city in Blouchestan of Iran, was chosen for studyin...
