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 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
Radiation and health - World Health Organization (WHO) 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
Ionizing radiation and health effects WHO fact sheet on ionizing radiation, health effects and protective measures: includes key facts, definition, sources, type of exposure, health effects, nuclear emergencies, WHO response
Rayonnements ionisants et effets sur la santé À mesure que les usages des rayonnements ionisants se multiplient, les dangers qu’ils peuvent comporter pour la santé, s’ils ne sont pas correctement utilisés ou confinés, augmentent
Radiation: 5G mobile networks and health 5G, or fifth generation, is the latest wireless mobile phone technology, first widely deployed in 2019 5G is expected to increase performance and a wide range of new applications, including strengthening e-Health (telemedicine, remote surveillance, telesurgery)
Radiation: Ionizing radiation - World Health Organization (WHO) Ionizing radiation is radiation with enough energy that to remove tightly bound electrons from the orbit of an atom, causing that atom to become charged or ionized Here we are concerned with only one type of radiation, ionizing radiation, which occurs in two forms: waves or particles There are several forms of electromagnetic radiation, which differ only in frequency and wavelength: Longer
Microsoft Word - Document1 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
Radiation: The Chernobyl accident Among those who survived radiation sickness, recovery took several years Many of them developed radiation-induced cataracts in the first few years after the accident Recent studies of the recovery operation workers indicate that opacities of the eye lens might result from radiation doses lower than previously expected (about 500 mSv)
Enhancing radiation safety culture in health care: guidance for health . . . Radiation safety culture in health care encompasses every action taken to improve the protection and safety of patients and personnel involved in medical exposure This publication provides a framework to establish, maintain and enhance radiation safety culture in health care It highlights patterns of organizational and individual thinking behaving which define a positive safety culture and
