Hey!
The question I need help on is describing how beta radiation is produced by a radioactive isotope.

Thank you so much

For beta- decay; A neutron decays into a proton. An Electron and Electron Anti-neutrino are released. The exchange particle is a W- Boson.

For Beta+ decay; A proton turns to a neutron. A positron and an electron neutrino are released. The exchange particle is a W+ boson.

Feynman Diagrams for these are available on google, just search the interaction/decay you want and you're bound to find an image.
I hope this helps!

Very good, but don't you think that it was a bit too extensive (in terms of the bosons)? it is GCSE level at least.

The isotope or nucleus of a radioactive element decays (splits up) into two new elements one of which is a Helium nucleus ejected at high energy. This ejected Helium atom is called beta radiation.

Erm... as far as I know that is alpha radiation, not beta radiation. A careless mistake by any chance?

That's Alpha.

That is what I have been saying. Everyone makes a mistake now and then.

GCSE you just need to know that a proton becomes a neutron and a positron is released or the other equation for \beta^-.

A-level you need to know that a neutrino or antineutrino is released to match up lepton numbers.

Any higher you need to know the process involving the W^{\pm}.
