The three types of nuclear emission
Core concepts and learning points for this section:
Syllabus Points
Core
- 5.2.2.1 Describe the emission of radiation from a nucleus as spontaneous and random in direction
- 5.2.2.2 Identify alpha ( α ), beta ( β ) and gamma ( γ ) emissions from the nucleus by recalling: (a) their nature (b) their relative ionising effects + (c) their relative penetrating abilities ( β are not included, β -particles will be taken to – refer to β )
Supplement
- 5.2.2.3 Describe the deflection of α -particles, β -particles and γ -radiation in electric fields and magnetic fields
- 5.2.2.4 Explain their relative ionising effects with reference to: (a) kinetic energy (b) electric charge www.cambridgeinternational.org/igcse 35 Subject content
