    Au-delà de certains seuils, les rayonnements peuvent altérer le fonctionnement des tissus et des organes et provoquer des effets aigus tels que des rougeurs cutanées, la perte de cheveux, des brûlures dues aux radiations ou un syndrome aigu d’irradiation Ces effets deviennent plus sévères lorsque la dose et le débit de dose augmentent
  • Radiation: Electromagnetic fields - World Health Organization (WHO)
    Exposure to electromagnetic fields is not a new phenomenon However, during the 20th century, environmental exposure to artificial electromagnetic fields has been steadily increasing as growing electricity demand, ever-advancing technologies and changes in social behaviour have created more and more artificial sources
  • 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)

  • Radiation: Ionizing radiation - World Health Organization (WHO)

  • 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
  • Exposure to radiation - World Health Organization (WHO)
    Exposure to radiation Ionizing (x-rays, radionuclides) and non-ionizing radiation (UV, lasers) exposure may occur in health-care settings and pose specific risk to the health and safety of health workers
