The 52nd Annual Meeting of the National Council on Radiation Protection and Measurements (NCRP) was held in Bethesda, MD, 11-12 April 2016, on the topic of "Meeting National Needs for Radiation Protection." This meeting was an outgrowth of the NCRP initiative "Where are the Radiation Professionals?" (WARP), which addresses looming shortages in professional personnel trained in the radiological ...

Considering current controversies regarding the health effects of low doses of ionizing radiation, study of the high background radiation areas such as Ramsar, Iran can help scientists better evaluate the validity of linear no-threshold (LNT) hypothesis. Ramsar is a coastal city in northern Iran with some areas known to have the highest levels of natural background radiation in the world. The m...

Background: The effect of natural background radiation on health is still controversial. However, it is clear that it depends on the dose received by the population. The estimation of external natural background gamma rays received by the population of Caspian coastal provinces in the northern part of Iran was the main goal of this study. Materials and Methods: Gamma rays was measured ...

n 1987 the International Agency for Research of Cancer (IARC) evaluated radon and its decay products as human carcinogens (1). Large epidemiologic studies conducted in Western Europe in the Õ90s showed that this radioactive gas accounted for 50 to 90% of a radiological dose (2). Very high residential concentrations of radon were measured in Sweden and Finland (3-5). They were 5,000 times higher...

BACKGROUND X-ray imaging is frequently used as diagnostic approach for scoliosis in children and adolescents. X-ray procedures are considered as justified only when expected benefits exceed related risks. While benefits are well known to physicians, radiological risk awareness can be vague, impeding an optimal communication with patients' parents and possibly leading to discomfort and anxiety. ...

Management of radiation mass casualty exposure that may occur as a result of nuclear or radiation accident will depend on the type of accident, and of the knowledge about the actual radiation exposure situation for those who might be involved. Management of the public after an accident in a nuclear or radiation installation will follow existing specific emergency plans, and will take advantage ...

human activities such as oil and gas production can enhance the natural level of naturally occurring radioactive materials (norm) in by-product and waste streams. iran has been among the top five oil producing countries since 2005. this high production rate emphasizes the importance of norm management to ensure the safety of humans and wildlife. petroleum storage and transport facilities are lo...
