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
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
Radiation: Ultraviolet (UV) radiation and skin cancer Due to their relative lack of skin pigmentation Caucasian populations generally have a much higher risk of getting non-melanoma or melanoma skin cancers than dark-skinned populations
Ultraviolet radiation - World Health Organization (WHO) Overview Ultraviolet radiation (UVR) can neither be seen nor felt While some people are exposed to artificial UVR sources (e g in medicine, industry and for disinfection and cosmetic purposes), everyone is exposed to solar UVR
Ultraviolet radiation - World Health Organization (WHO) Ultraviolet (UV) radiation covers the wavelength range of 100–400 nm, which is a higher frequency and lower wavelength than visible light UV radiation comes naturally from the sun, but it can also be created by artificial sources used in industry, commerce and recreation
Radiation: The Chernobyl accident - World Health Organization (WHO) The average effective doses among 530,000 recovery operation workers was 120 millisieverts (mSv); among 115,000 evacuees, 30 mSv; among residents of contaminated areas, 9 mSv (during the first two decades after the accident); and among residents of other European countries, less than 1 mSv (in the first year after the accident)
Radiation: The known health effects of ultraviolet radiation UV radiation can cause short- and long-term health effects on the skin In addition to the well-known short-term effects such as sunburn or allergic reactions, long-term effects like skin cancer represent a chronic health risk
Radiation: 5G mobile networks and health - World Health Organization (WHO) 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)
