Background: Measurement of the radiation dose distribution is important in assessing the health risk a population and serve as reference in documenting changes to environmental radioactivity in soil due to man-made activities. Materials and Methods: The activity concentration of 238U, 232Th and 40K in soil samples obtained from different locations in Ajaokuta Local Government area was measured ...

Background: Although ionizing radiation is widely used to diagnose many diseases, the relevant hazards are known to be as an important limitation of its application. It is believed that the awareness of ionizing radiation dose values is one of the main stages in patient's radiation protection. The purpose of this study has been to investigate the level of physicians' knowledge about radiation d...

Introduction: There are natural and artificial radioactive nuclei in our environment, as well as in the structure of the living organism. Currently, industrial and municipal pollution has also an impact on increasing the level of radiation. The present study investigated the effect of inlet water from Arak Wastewater Treatment Plant on international Meighan Wetland and...

OBJECTIVE In this study, we evaluated the knowledge and perception and mitigation of hazards involved in radiological examinations, focusing on healthcare personnel who are not in radiation-related occupations, but who use ionising radiation as a part of their work. METHODS A questionnaire was applied to physicians, nurses, technicians and other staff working in different clinics that use rad...

OBJECTIVE To document the ability of public health laboratories to respond to radiological emergencies. METHODS The Association of Public Health Laboratories developed, distributed, and analyzed two separate surveys of public health laboratories representing the 50 US states and major nonstate jurisdictions. The 2009 All-Hazards Laboratory Preparedness Survey examined overall laboratory capab...

Introduction Ionizing radiation comes from natural (radioactivity and cosmic radiation) or artificial sources. The ionizing radiation, which includes the X-ray radioactive isotopes produced in nuclear reactors, has many applications, notably industries, investigation medicine sectors, turning health professionals into exposed workers. Case description A case of a 61-year-old women, radiologic t...

Background: Natural radionuclides in rock samples, primarily 238U (uranium), 232Th (thorium) and 40K (potassium), are the main source of radiation exposure to workers and general public and their measurement is of paramount importance from radiation protection point of view. Materials and Methods: Gamma spectrometry using HPGe detector was used to measure the radioactivity and assess the radiol...
