conclusions comprehensive protection programs with on-the-job training courses for staff members are strongly recommended, as well as, the provision of radiological shields and gonad shielding protocols in radiology departments to reduce the patient’s radiation dose during radiological examinations. materials and methods a retrospective, observational cross-sectional study on the application of...
background: designing and shielding of an appropriate radiography room has been one of the major concerns of radiation scientists since the first decade after the invention of x-rays. recently, report no.147 of national council on radiation protection and measurements (ncrp) has been published. in this study the researchers have investigated the effect of new report recommendation on primary an...
background the use of shielding tools and x-ray beam collimator has extensively been advocated as effective methods to reduce radiation exposure to patients underwent radiological procedures. the aim of this study was to address the use of these protection measures during infant chest radiography. material and methods 348digital and/or analogue infant chest radiographs were reviewed that perfor...
BACKGROUND Gonad shielding has been extensively advocated during pelvic radiography at or below reproductive ages. The popular practice of gonad shielding is placement of a lead shield in the midline of the pelvis. The aim of this study was to address the prevalence of gonad shielding and find out whether the current practice of gonad shielding can be considered as an effective method to reduce...
Neutron radiography has long been used in various scientific investigations and industrial applications that require thermal neutrons for characterization. Different kinds of sources such as radioactive sources, portable and accelerator based neutron generators and nuclear reactors can be used to provide thermal beam of neutrons suited for neutron radiography. Among the different varieties of n...
OBJECTIVE To re-evaluate gonad shielding in paediatric pelvic radiography in terms of attainable radiation risk reduction and associated loss of diagnostic information. METHODS A study on patient dose and the quality of gonad shielding was performed retrospectively using 500 pelvic radiographs of children from 0 to 15 years old. In a subsequent study, 195 radiographs without gonad shielding w...
