Wherever we are, we are exposed to radiation. Sometimes we feel them, often we don't even notice them. People have always lived with natural radiation. Radiation has an effect on people and their health. But how exactly does it work, when and how do you have to protect yourself? The Federal Office f
In this video from NOVA’s Sun Lab, examine how scientists use electromagnetic radiation to learn about the Sun. The process of nuclear fusion in the core of the Sun produces energy in the form of electromagnetic radiation, or light. The wavelength of photons (particles that carry electromagnetic ene
Our sun. Their radiation provides light and warmth and thus promotes well-being. But the sun's ultraviolet radiation can also be harmful to health. Original: "Federal Office for Radiation Protection" Original: German. All translations in this video have been done by the alugha AI.
Tim's sister Vicky works in radiation research. She shows him where we encounter radiation everywhere - and what it actually is. #strahlenschutz #strahlung #radioaktivität #radioaktiv #uv #mobilfunk #handy #röntgen Original: "Federal Office for Radiation Protection" Original: German. All translat
Wi-Fi, power lines, smartphones – electromagnetic fields accompany us in everyday life. What do people think about the dangers? What do they want to say to those responsible? The Federal Office for Radiation Protection asked people about this in 2019. Here are their answers. Original: "Federal Offi
If there is a suspicion of increased radiation exposure, there are various ways to determine it. One possibility is biological dosimetry, which can be used to estimate the level of individual radiation exposure. In the video, Dr. Ulrike Kulka explains how radiation exposure in humans can be biologic
Explore natural and human made light sources in the environment in this live-action video produced by WGBH. The video can help children observe and identify light sources and describe objects that are visible in the light’s path. Support materials include: Background Reading, Teaching Tips, and Dis
Observe a group of children using light to communicate over a distance in this live-action video produced by WGBH. Use the video to observe strategies for using light to communicate across a distance as well as to design a light signal code to help you communicate to solve a problem from different l
Our stationary probes measure the local dose rate at a specific location around the clock. So we always know how much it is radiating at that place. But in order to determine what is radiating there - i.e. which substances - we need a different kind of measurement. We carry them out at regular inter

A high dose of radiation can damage the human organism or even lead to acute illnesses. Even years or decades later, so-called stochastic radiation effects can occur, which can often result in cancer. In the video, Dr. Maria Schnelzer explains how radiation affects humans and explains the health con
