Radiation - World Health Organization (WHO) Ionizing radiation is a type of energy released by atoms that travels in the form of electromagnetic waves (gamma or X-rays) or particles (neutrons, beta or alpha) Ionizing radiation can remove electrons from the atoms, i e they can ionize atoms In terms of natural radiation sources, there are more than 60 different naturally occurring radioactive materials present in the environment, with
Radiation and health - World Health Organization (WHO) Radiation is the emission of energy as electromagnetic waves or moving subatomic particles Natural radiation comes from many naturally occurring radioactive materials found in soil, water, air and in the body Every day, people inhale and ingest forms of radiation from air, food and water Today, the most common artificial sources of human exposure to radiation are X-ray machines and
Ionizing radiation and health effects What is ionizing radiation? Ionizing radiation is a type of energy released by atoms that travels in the form of electromagnetic waves (gamma or X-rays) or particles (neutrons, beta or alpha) The spontaneous disintegration of atoms is called radioactivity, and the excess energy emitted is a form of ionizing radiation
Exposure to radiation - World Health Organization (WHO) Exposure to radiation Ionizing (x-rays, radionuclides) and non-ionizing radiation (UV, lasers) exposure may occur in health-care settings and pose specific risk to the health and safety of health workers
Radiation: The Chernobyl accident - World Health Organization (WHO) WHO collaborates with the IAEA on a number of areas including the medical use of radiation, radiation protection and the safety of the public and workers, and radio-nuclear emergency preparedness and response Under the auspices of the UN Chernobyl Forum, WHO carried out its own independent health assessment of the accident
Radiation and health - World Health Organization (WHO) Radiation and health About us Within the WHO global strategy described in the GPW13, towards the achievement of the sustainable development goals, the WHO Radiation and Health Unit works to strengthen radiation protection of the public, patients and workers worldwide
Radiation and health - World Health Organization (WHO) Radiation and health We work to strengthen radiation protection of the public, patients and workers worldwide We provide Member States with evidence-based guidance, tools and technical advice on public health issues related to ionizing and non-ionizing radiation
Global experts convene in Vienna to discuss radiation protection in . . . The conference on radiation protection in medicine marks a milestone in assessing progress since the Bonn Call for Action, launched in 2012 to strengthen global radiation protection in medicine Over the past decade, international and scientific organizations, regulators and professional societies have worked to implement its ten priority actions
Document1 - World Health Organization (WHO) Radiation exposure Ionizing radiation exposure is measured as "absorbed dose" in gray (Gy) The "effective dose" measured in sievert (Sv) takes account of the amount of ionizing radiation energy absorbed, the type of radiation and the susceptibility of various organs and tissues to radiation damage
Guidance on radiation and health - World Health Organization (WHO) Radiation emergencies Radiation emergencies (including radiological and nuclear emergencies) may result from technological incidents, natural disasters, transport accidents, acts of terrorism, polluted environments, and may involve over-exposure from external sources or internally from contaminated air, drinking-water, foods and products
