Properties for alpha beta and gamma ray particles:

Question 1

What is the range of air for the radiation types?

Answer 1

• Alpha Particles: 5cm in the air before they collide with air particles and stop.
• Beta Particles: Further. 15cm in the air before stopping.
• Gamma Radiation: Several metres.

Question 2

What is the penetrating power of the different types of radiation?

Answer 2

• Alpha Particles: Stopped by a sheet of power.
• Beta Particles: Few mm of alliminium.
• ## Gamma Rays: Several cm of Lead.

Question 3

What is the ionising power of the types of radiation?

Answer 3

• When radiation collides with atoms this can cause atoms to loose elctrons + form ions.
• Alpha: Strongly ionisig.
• Beta Particles: Quite strongly ionising.
• Gamma Rays: Weakly ionising.
