In the present day scenario, radiation dose from medical imaging has come under scrutiny both in the medical and public press. This is as a result of the increased cancer risks associated with radiation as well as cases of excess radiation exposure from advance radiological equipment like CT scans. Therefore, this study assessed doctors’ knowledge on patients’ radiation doses during radiologica...

The widespread damage and loss of life caused by the March 11th earthquake-generated tsunami in Japan, and the resulting emergency at the Fukushima Daiichi nuclear power facility, raise once again the question of the role of knowledgeable civilians in responding to public health emergencies. In the case of a radiological emergency, medical physicists are among the more knowledgeable individuals...

Background: One of the main sources of exposure to radiation is terrestrial radionuclides in the environment. These radioisotopes are present in the Earthchr('39')s crust and can be increased by human activity such as mining of coal, oil, and minerals. Materials and Methods: In this study, 39 soil samples including virgin and cultivated were collected from around of the Shazand Refinery Complex...

OBJECTIVE To compare the total work-related radiation dose in our department of radiology with the dose in Dutch residences, taking x-ray radiation, external natural radiation and radon into account. METHODS Annual doses due to exposure to x-rays and external natural radiation were derived from the measured personal dose equivalent [H(p)(10)] of 144 workers. Additionally, departmental (222)Rn...

A summary is provided of presentations and discussions at the NASA Radiation Biomarker Workshop held September 27-28, 2007 at NASA Ames Research Center in Mountain View, CA. Invited speakers were distinguished scientists representing key sectors of the radiation research community. Speakers addressed recent developments in the biomarker and biotechnology fields that may provide new opportunitie...

In the paper it demonstrates that for more precise and comprehensive interpretation under the framework of biospheric concept, the anthropocentric paradigm, being now the one of the basic principles in radiation protection, should be reformulated and amended (an immediate switch to ecological concept involves significant changes and calls for solution of very complicated scientific problems). I...

Introduction: Ionizing radiation has long-term risks, especially cancer. Since physicians request radiological examinations for patients, they need to be aware of its benefit and also risks. The aim of this study was to assess the overall knowledge of physicians in Yazd province about the radiation risks associated with diagnostic imaging procedures. Material and Methods: In this descriptive ...

Late-onset effects of exposure to ionising radiation on the human body have been identified by long-term, large-scale epidemiological studies. The cohort study of Japanese survivors of the atomic bombings of Hiroshima and Nagasaki (the Life Span Study) is thought to be the most reliable source of information about these health effects because of the size of the cohort, the exposure of a general...

INTRODUCTION The global threat of a chemical, biological, radiological, or nuclear (CBRN) disaster is an important priority for all government agencies involved in domestic security and public health preparedness. Radiological/nuclear (RN) attacks or accidents have become a larger focus of the United States Food and Drug administration (US FDA) over time because of their increased likeliness. C...

Soil acts as a source of continuous radiation exposure to human and as a medium of migration for transfer of radionuclides to the biological systems hence causes the radiological contamination in the environment. So, it is necessary to study the natural radioactivity in soil to assess the dose due to terrestrial gamma radiation levels in order to know the health risks. The Primordial Radioactiv...
