Introduction Radiation protection is an important safety issue for radiographers and patients. The aim of this study was to assess the observance of radiation protection regulations in radiology departments of Kermanshah University of Medical Sciences, Kermanshah, Iran. Materials and Methods In total, 48 radiographers and 8 radiography rooms were evaluated in three hospitals of Kermanshah, Iran...
Introduction: Best radiography practice involves operational optimal machine performance, delivering cost-effective healthcare services under appropriate safety conditions for workers and the public. The present study aimed to investigate the safety status of diagnostic X-ray installations in Mizoram, India. Material and Methods: Lineari...
In the present study, the alteration in the sleep EEG in rats due to chronic exposure to low-level non-thermal electromagnetic radiation was investigated. Two types of radiation fields were used; 900 MHz unmodulated wave and 900 MHz modulated at 8 and 16 Hz waves. Animals has exposed to radiation fields for 1 month (1 h/day). EEG power spectral analyses of exposed and control animals during slo...
conclusion attending radiologists could diagnose acute appendicitis accurately on ne-ldct. performance of senior residents on ne-ldct is better than junior residents and comparable to attending radiologists. results diagnostic performances for acute appendicitis were not statistically different for attending radiologists at both examinations. better performance was noted on the ce-sdct with a b...
It is well known that radioactive rays may cause damage to the human body. Progress in modern medicine has led to an increased risk of therapeutic and diagnostic radiation exposure of patients. Although clear evidence of a radiation dose-dependent risk of chronic myeloid leukaemia, particularly for patients exposed to radiation at a young age, has been established, it is not known whether radia...
Quasielectrostatic whistler wave radiation from the hot electron emission of a laser-produced plasma
Measurements are presented of radiated wave electric fields which result from the creation of a dense, laser-produced plasma within a large, uniform background magnetoplasma. The radiated field patterns are consistent for waves propagating along the quasielectrostatic branch of the whistler wave dispersion curve calculated from the background plasma parameters. The energy source of these waves ...
Unstable isotopes and their capacity to emit ionizing radiation have been employed in clinical practice not only for diagnostic, but also for therapeutic purposes, with significant contribution in several fields of medicine and primarily in the management of oncologic patients. Their efficacy is associated with their ability to provide the targeted delivery of ionizing radia‐ tion for a determi...
Ultrasonography as an imaging modality in dentistry has been extensively explored in recent years due to several advantages that diagnostic ultrasound provides. It is a non-invasive, inexpensive, painless method and unlike X-ray, it does not cause harmful ionizing radiation. Ultrasound has a promising future as a diagnostic imaging tool in all specialties in dentistry, for both hard and soft ti...
