Nuclear Physics: Radioactive Decay 2
Flashcards do conjunto (8)
- 1Radioactive DecayWhen radiation is emitted from a nucleus, the nucleus undergoes decay
- 2Alpha emissionEmission of a helium nucleus from a large atom
- 3Beta emissionThe emission of an electron when a neutron decays into a proton
- 4Gamma emissionThe emission of high energy photons from an unstable nucleus
- 5Activity of a radioactive sorceNumber of nuclei decaying per second
- 6Half-lifeTime taken for half of the nuclei of a source to decay
- 7Law of radioactive decayThe activity of a radioactive source is proportional to the number of undecayed nuclei present
- 8Formula of radioactive decayA = λ N
Informações
- Descrição
- This flash card deck covers radioactive decay, alpha, beta and gamma emission, activity of a radioactive source and half-life. This can be used alongside the note on radioactive decay and radioactivity and the mind map on nuclear physics
