background: the natural radionuclides are always present in soil and care needs to be taken to minimize the radiation dose to humans. these radionuclides are mostly gamma ray emitting radionuclides which contribute to the radiation dose in long term behavior of radionuclides in soil. health hazards associated with natural radioactivity are of great concern and it is necessary to assess risk due...
introduction the potential hazards posed by exposure to radiation from radon have been of great concern worldwide, since it is especially associated with increased risk of lung cancer. some radioisotopes of radon progeny deposited in the human lungs emit β particles followed by the γ rays. while γ rays are comparatively less damaging to the respiratory system than α and β particles, it is the p...
Background and purpose: Knowledge on the risks of radiation during diagnostic imaging is necessary to protect patients against the hazards of ionizing radiation. The aim of this study was to investigate the level of knowledge of interns, radiology residents, radiology students, and staff about radiation doses received by patients in radiological examinations. Materials and methods:...
