Question

what is the nature of beta radiation

Answer 1

Beta-particle radiation consists of fast moving electrons. Every Beta particle carries either one negative or one

positive electronic charge ( +/-

1.6 × 10-19 coulomb: -e, +e). They are affected by electric and magnetic fields.

The speed depends on the source, but it can be up to 90% of the speed of light.

Beta particles can penetrate up to 1 m of air. They are stopped by a few millimetres of aluminium or perspex.

Their ionising capacity is much less than that of alpha radiation. They are very dangerous if they are ingested.
