Phase: Introduction (5 min)

Content: Alpha radiation Alpha radiation is the least penetrating. It can be stopped - or absorbed - by just a sheet of paper. Beta radiation Beta radiation can penetrate air and paper. It can be stopped by a thin sheet of aluminium.

Gamma radiation Gamma radiation is the most penetrating. Even small levels can penetrate air, paper or thin metal. Higher levels can only be stopped by many centimeters of lead or many meters of concrete Structuring (30min)

A heavy radioactive nucleus (uranium235) is bombarded with a neutron, it split into two smaller nuclei of different elements. This process called nuclear fission 19

Assessment (20minute)

Nuclear fission is the splitting of heavy nucleus into 2 lighter nuclei that have similar mass. Energy produced during nuclei fission is called nuclear energy. Nuclear energy can be produced through nuclear fission of a radioactive element in a nuclear reactor.
