Demonstrating radiation detectors | Physics - How to Survive in Space

Dr Kevin Fong shows how a Geiger-Muller tube can detect ionising radiation (but not the type of radiation), but that high-tech detectors on the International Space Station can - a vital part of protecting astronauts from radiation outside of Earth's atmosphere.

Aboard the International Space Station, UK astronaut Tim Peake monitors his radiation exposure using a TimePix detector. Using a student from the audience to help, Kevin shows that a Geiger-Muller tube can be used to detect ionising radiation; a laboratory notebook used by the scientist who developed medical X-ray imaging technology is found to be highly radioactive. But the detectors used by astronauts can detect not just the number of particles that hit them, but also the types of ionising particle that hit them, and Kevin demonstrates this on screen. This clip is from the BBC series How to Survive in Space. From the historic Royal Institution christmas Lectures 2015, space doctor Kevin Fong takes us on a ride from launch to orbit and the cosmos beyond, with help from British astronaut Tim Peake.

Key Stage 3 After watching the clip, ask students to research the three types of ionising radiation and how they can be stopped. Key Stage 4 Before watching the clip, ask students to recall the three types of ionising radiation and what they already know about them. What are the hazards to astronauts aboard the ISS from ionising radiation? This clip will be relevant for teaching Physics. This topic appears at KS3 or in OCR, Edexcel, AQA, WJEC KS4/GCSE in England and Wales, CCEA GCSE in Northern Ireland and SQA National 4/5 in Scotland. ===================== For more clips from other subjects at the BBC Teach YouTube channel: http://www.youtube.com/bbcteach More resources for teachers from the BBC: http://www.bbc.co.uk/teach More from BBC Learning Zone: http://www.bbc.co.uk/learningzone More resources from BBC Bitesize: http://www.bbc.co.uk/education ===================== Subscribe to create your own customised playlists, and get notified about our latest clips.
