- 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)
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
- 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
- Radiation: Ionizing radiation - World Health Organization (WHO)
Energy emitted from a source is generally referred to as radiation Examples include heat or light from the sun, microwaves from an oven, X rays from an X-ray tube and gamma rays from radioactive elements Ionizing radiation can remove electrons from the atoms, i e it can ionize atoms

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: 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: 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)
