- 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
- Ionizing radiation and health effects - World Health Organization (WHO)
People are also exposed to natural radiation from cosmic rays, particularly at high altitude On average, 80% of the annual dose of background radiation that a person receives is due to naturally occurring terrestrial and cosmic radiation sources Background radiation levels vary geographically due to geological differences
- Radiation: Ionizing radiation - World Health Organization (WHO)
Radiation is permanently present throughout the environment - in the air, water, food, soil and in all living organisms In fact, a large proportion of the average annual radiation dose received by people results from natural environmental sources Each person is exposed to an average of 2 4 mSv per year of ionizing radiation from natural sources
- 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: Electromagnetic fields - World Health Organization (WHO)
The Federal Office for Radiation Safety in Germany recently measured the daily exposure to magnetic fields of about 2000 individuals across a range of occupations and public exposures All of them were equipped with personal dosimeters for 24 hours The measured exposure varied widely but gave an average daily exposure of 0 10 µT
- Radiation: 5G mobile networks and health - World Health Organization (WHO)
The project investigates the health impact of exposure to electric and magnetic fields in the frequency range 0-300 GHz and advises national authorities on EMF radiation protection WHO advocates for further research into the possible long-term health impacts of all aspects of mobile-telecommunications
- Radiation: The Chernobyl accident - World Health Organization (WHO)
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) Cancers
- Radiation: Ultraviolet (UV) radiation - World Health Organization (WHO)
Everyone is exposed to UV radiation from the sun and an increasing number of people are exposed to artificial sources used in industry, commerce and recreation The sun is by far the strongest source of ultraviolet radiation in our environment Solar emissions include visible light, heat and ultraviolet (UV) radiation
