Measurement technologies are getting increasingly sensitive -- but what does it mean for risk when we can measure the smallest amount of a substance in the stuff we eat, drink and breathe? Note: In talking about the hypothetical risk from the hypothetical substance Greensave, the video talks abou
The right sun protection is important if you want to avoid negative long-term consequences of too much UV radiation. But what is the best way to protect yourself? In three minutes, the animation shows what needs to be considered for sun protection. Original: "Federal Office for Radiation Protection
Not all textiles provide equally good protection against UV radiation. So how do I know if my parasol or my clothes offer real protection? You asked, we are happy to answer in the video. More information about sun protection, UV protection and skin cancer prevention can also be found on https://www.
NASA recently announced a plan to send a probe to our Sun! Is this even worth the money? Click here to see more videos: https://alugha.com/LifeNoggin Follow Us! https://twitter.com/LifeNoggin https://facebook.com/LifeNoggin https://www.instagram.com/lifenoggin Life Noggin is a animated educationa
What are the ethical issues that emerge as our ability to detect chemicals in the environment around us improves? This week's risk bites looks at the ethical dimension of the measurement conundrum -- when our ability to detect stuff outstrips our understanding of what to do with the information. Th
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
Our Sun is an ordinary star — just one of billions of stars in our galaxy alone. However, as our own star, the Sun holds special status for us and is essential to our existence. The Sun's gravity holds the solar system together, and nuclear fusion within the Sun supplies the energy for life on Earth
The greater use of renewable energies from solar and wind requires the expansion of the electricity grids. Radiation protection plays an important role in this because electric and magnetic fields are generated by additional high-voltage lines. How great are possible loads from high-voltage lines? W
Four pillars of UV protection: The Federal Office for Radiation Protection explains how UV protection is becoming even more common practice in municipalities, schools and sports grounds. Climate change is already having a noticeable influence on UV radiation and thus on people's UV exposure. For ex
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

The polarimeter is an important measuring instrument for determining the specific angle of rotation of an optically active substance. This first video is exclusively about the construction of a polarimeter. Afterwards, a short measurement is also carried out. Only in another video will I explain how
