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. 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. Human-made radiation sources are widely used in medicine, industry, and research.
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). What is 5G?
Prenatal exposure to ionizing radiation may induce brain damage in foetuses following an acute dose exceeding 100 mSv between weeks 8-15 of pregnancy and 200 mSv between weeks 16-25 of pregnancy. Before week 8 or after week 25 of pregnancy human studies have not shown radiation risk to fetal brain development.
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. About us.
According to the UNSCEAR report, the Chernobyl accident caused a number of severe radiation effects almost immediately. Of 600 workers present on the site during the early morning of 26 April 1986, 134 received very high doses (0.8-16 Grey) and suffered from acute radiation sickness. Of those, 28 workers died in the first three months.
Solar emissions include visible light, heat and ultraviolet (UV) radiation. Just as visible light consists of different colours that become apparent in a rainbow, the UV radiation spectrum is divided into three regions called UVA, UVB and UVC. As sunlight passes through the atmosphere, all UVC and most UVB is absorbed by ozone, water vapour ...
Radar systems detect the presence, direction or range of aircraft, ships or other, usually moving objects. This is achieved by sending pulses of high frequency electromagnetic fields (EMF). Invented some 60 years ago, radar systems have been widely used for navigation, aviation, national defence and weather forecasting.
Given the immense number of people who use mobile phones, even a small increase in the incidence of adverse effects on health could have major public health implications. Because exposure to the radiofrequency (RF) fields emitted by mobile phones is generally more than a 1000 times higher than from base stations, and the greater likelihood of ...
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.
