Atomic Structure And Radiation Flashcards
(4 cards)
1
Q
The 4 types of radiation that can be emitted during radioactive decay
A
Alpha
Beta
Gamma
Neutrons
2
Q
Alpha: penetrating power, ionising ability, range in air
A
Low penetrating power. Stopped by paper
High ionising ability (positively charged, large particle)
Low range in air <5cm
3
Q
Beta: penetrating power, ionising ability, range in air
A
Medium penetrating power (stopped by aluminium)
Moderate ionising ability (smaller than alpha, less likely to collide)
Medium range in air (few metres)
4
Q
Gamma: penetrating power, ionising ability, range in air
A
High penetrating power (stopped by concrete)
Low ionising ability (they’re unlikely to collide with atoms)
Infinite range in air
