Question

(d) In this question you will be assessed on using good English, organising information clearly and using specialist terms where appropriate. The type of radiation emitted from a radioactive source can be identified by comparing the properties of the radiation to the properties of alpha, beta and gamma radiation. Describe the properties of alpha, beta and gamma radiation in terms of their: • penetration through materials • range in air • deflection in a magnetic field.

Answer 1

Hey!

I did this question and have the answers/potential things you can write!

XD

Step-by-step explanation:

Here!

structure

•alpha particle consists of a helium nucleus

•alpha particle consists of 2 protons and 2 neutrons

•a beta particle is an electron

•a beta particle comes from the nucleus

penetration

•alpha particles are very poorly penetrating

•alpha particles can penetrate a few cm in air

•alpha particles are absorbed by skin

•alpha particles are absorbed by thin paper

•beta particles can penetrate several metres of air

•beta particles can pass through thin metal plate / foil

•beta particles can travel further than alpha particles in air

•beta particles can travel further than alpha particles in materials eg metals

deflection

•alpha particles and beta particles are deflected in opposite directions in an electric field

•beta particles are deflected more than alpha particles

•alpha particles have a greater charge than beta particles but beta particles have much less mass or beta particles have a greater specific charge than alpha particles

Hope this helps!

Sorry if it's a bit too long!
