International Commission on Radiological Protection (ICRP), an independent international organization established in 1925, develops, maintains, and elaborates radiological protection standards, legislation, and guidelines. United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) provides scientific evidence. World Health Organization (WHO) and International Atomic Energy...

The German Meteorological Service (DWD) is charged with tasks of radiation protection by the Law of the Deutscher Wetterdienst (1955, 1998), the Precautionary Radiation Protection Act (1986) and the Radiation Protection Ordinance (2001). Since 1955 the DWD is responsible for the surveillance of radioactivity in the atmosphere realized by measuring the radioactivity as well as analyzing the mete...

The U.S. Environmental Protection Agency (EPA) bases its risk assessments, regulatory limits, and nonregulatory guidelines for population exposures to low level ionizing radiation on the linear no-threshold (LNT) hypothesis, which assumes that the risk of cancer due to a low dose exposure is proportional to dose, with no threshold. The use of LNT for radiation protection purposes has been repea...

The development of a system capable of ensuring adequate protection of the environment from the harmful effects of ionising radiation is at present particularly debated. This need comes both from a restrictive consideration of the environment in the so far existing system for human radioprotection, and the planetary-wide growing concerns about man's technogenic influence on his environment whic...

During the last decade or so, the topic of environmental protection from ionising radiation has become a major issue within the field of radiological protection. The change of focus from a purely anthropocentric approach has led to the development and availability of bespoke methodologies for the assessment of impacts on wildlife from radioactive contaminants. The application of such assessment...

BACKGROUND Although ionizing radiation is very important in diagnostic and treatment of many diseases, the hazards of this radiation are considerable and irrefutable. One of the main stages in radiation protection is knowledge about radiation dose in radiological investigation. The aim of this study was to determine the physicians' knowledge in radiological examinations. MATERIAL AND METHODS ...

Radiation is the transmission of energy through space and matter. There are several forms of radiation, including ionizing and nonionizing. X-rays are the ionizing radiation used extensively in medical and dental practice. Even though they provide useful information and aid in diagnosis, they also have the potential to cause harmful effects. In dentistry, it is mainly used for diagnostic purpos...

The current radiation protection framework provides an adequate basis for protecting workers, the public and the environment. Nevertheless, international and national radiation protection organizations are presently engaged in updating, clarifying and enhancing radiation protection principles –and rightly so, given our culture of pursuing excellence in radiation safety through a process of cont...

The International Commission on Radiological Protection (ICRP) has formulated recommendations concerning the philosophy of radiation protection. This philosophy has been used by the IAEA, World Health Organization (WHO), International Labour Organisation (ILO), and the Nuclear Energy Agency of the Organisation for Economic Co-operation and Development (NEA/OECD) for preparation in 1982 of the r...
