Ionising radiation

Beta

-
-
Few metres of range in air, absorbed by 5mm sheet of aluminium
-
-
Nuclear fusion
Two light nuclei collide at high speed and fuse to create a larger, heavier nucleus
-
Expensive and hard to build because temperatures and pressures have to be high. To overcome the electrostatic repulsion
The heavier nucleus does not have as much mass as the two separate lighter nuclei as some of the mass of the lighter nuclei turned into energy
-
-
Nuclear fission
Splitting a large, unstable nucleus
-
-
-
Causing a chain reaction to happen, therefore more fission
