Build your knowledge and consider the issues surrounding nuclear power. .
Half-life - The time it takes for the number of nuclei in a sample to halve.
Radiation involves transfer of heat via infra red waves, unlike thermal conduction and convection which need the vibration or movement of particles.
To anyone who’s still procrastinating about doing revision, you need to listen to this advice: 174. Anisha Rai. Fig.
. Every. The table shows some features of the four main types of radiation: Type of radiation.
CORE OBJECTIVES: Know what is meant by background radiation. .
Choose a topic you know you need to work.
Join. The electromagnetic spectrum is arranged in a specific order based on the wavelengths or frequencies.
Edexcel Specification Section 7: Radioactivity and particles b) Radioactivity describe the structure of an atom in terms of protons. Radioactive particles decay and release alpha, beta and gamma radiation - natural and artificial sources of background radiation.
Uses of Electromagnetic Waves. Join. Listen along as we explore all you need to know to get the best in your exams.
3. . These sources tend to be from nuclear weapons testing and nuclear accidents. . r/GCSE.
