Dosimetry of Occupational Radiation around Panoramic X-ray Apparatus
Background: Panoramic imaging is one of the most common imaging methods in dentistry. Regarding the side-effects of ionizing radiation, it is necessary to survey different aspects and details of panoramic imaging. In this study, we compared the absorbed x-ray dose around two panoramic x-ray units: PM 2002 CC Proline (Planmeca, Helsinki, Finland) and Cranex Tome (Soredex, Helsinki, Finland).<br ...
متن کاملObserving scattered X-ray radiation from gamma-ray bursts: a way to measure their collimation angles
An abstract should be given here are observational facts and theoretical arguments for an origin of gamma-ray bursts (GRBs) in molecular clouds in distant galaxies. If this is true, one could detect a significant flux of GRB prompt and early afterglow Xray radiation scattered into our line of sight by the molecular and atomic matter located within tens of parsecs of the GRB site long after the ...
متن کاملA new shielding calculation method for X-ray computed tomography regarding scattered radiation
The goal of this study is to develop a more appropriate shielding calculation method for computed tomography (CT) in comparison with the Japanese conventional (JC) method and the National Council on Radiation Protection and Measurements (NCRP)-dose length product (DLP) method. Scattered dose distributions were measured in a CT room with 18 scanners (16 scanners in the case of the JC method) for...
متن کاملScattered radiation doses absorbed by technicians at different distances from X-ray exposure: Experiments on prosthesis.
UNLABELLED This work aimed to investigate the spatial distribution of scattered radiation doses induced by exposure to the portable X-ray, the C-arm machine, and to simulate the radiologist without a shield of lead clothing, radiation doses absorbed by medical staff at 2 m from the central exposure point. MATERIAL AND METHOD With the adoption of the Rando Phantom, several frequently X-rayed b...
متن کاملEvaluation of X-Ray Radiation Levels in Radiology Departments of Two Educational Hospitals in Ahvaz, Iran
Introduction: The ionizing radiation is increasingly applied in various fields for industrial and medical purposes due to its benefits. The aim of this study was to measure the radiation levels in six radiology departments of two educational hospitals in Ahvaz, Iran. Materials and Methods: The radiation levels were measured at six locations of six radiology departments, including behind the pat...
