- 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 - World Health Organization (WHO)
Radiation is energy that travels in the form of waves or particles and is part of our everyday environment People are exposed to radiation from cosmic rays, as well as to radioactive materials found in the soil, water, food, air and also inside the body
- 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
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 Unstable elements which disintegrate and emit ionizing radiation are called
- 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: 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
- Use of potassium iodide for thyroid protection during nuclear or . . .
During a nuclear accident, radioactive iodine may be released to the environment in a plume or cloud and subsequently contaminate soil, surfaces, food and water
- 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)
