Flashcards
Alpha, Beta and Gamma Radiation
Cards in this deck (13)
- 1What are the three types of radiation emitted during decay?- Alpha α
- Beta β
- Gamma γ - 2What is the structure of an alpha particle?2 protons + 2 neutrons
- 3What is the charge and mass of an alpha particle?- Charge = +2
- Mass = 4 - 4Which element is an alpha particle the nucleus of?Helium
- 5What is the range in air of an alpha particle?A few cm, will be stopped by skin or paper
- 6What is a beta particle and how is it formed?An electron ejected from the nucleus when a neutron breaks down into a proton and an electron
- 7What is the charge and mass of a beta particle?- Charge = -1
- Mass = 0 (negligible) - 8What is the range in air of a beta particle?1 metre, will be stopped by a few mm of aluminium
- 9What is a gamma ray?En electromagnetic wave
- 10What is the charge and mass of a gamma ray?- Charge = 0
- Mass = 0 - 11What is the range in air of a gamma ray?Unlimited in air, will be stopped by a few feet of concrete
- 12Define ionisationWhere nuclear radiation travels through a material and collides with the atoms, knocking electrons off and creating ions
- 13Give the three types of radiation in order from most to least ionising- Alpha
- Beta
- Gamma
