Radiation is a form of energy released in the form of rays, particles, or waves. It can be found all around us, from the sun and stars, to man-made sources like cell phones, computers, and nuclear power plants. Radiation can be both beneficial and harmful. It can be used to diagnose and treat illnesses and diseases, or it can cause long-term health problems such as cancer. On this page, you can find the latest news, articles, and videos about radiation and how it affects us.
Astronomers using NASA's Chandra X-ray Observatory, as well as ESA's XMM-Newton, are studying the radiation emitted by nearby stars to establish whether or not an exoplanet orbiting those stars could be habitable.
Terahertz radiation frequency lies in the range of 0.1–10 THz and known as THz Gap . THz radiation is novel type radiation and has several unique properties like as quantum and electronic properties of materials, nonionizing properties, easily penetrates through most polymeric materials.
The impact of enhanced cosmic radiation from a nearby supernova on Earth’s biosphere would be limited by the resulting increase in cloud and aerosol abundance, according to Earth system modelling that accounts for atmospheric aerosols formation processes
Observation of Chang’e-5 lunar soils reveals that the formation of small and large metallic iron particles with distinct optical effects is governed by independent space weathering processes: solar wind irradiation and micrometeorite impacts, respectively.
The space environment is harsh and full of extreme radiation. Scientists designing spacecraft and satellites need materials that can withstand these conditions.
