MEASURING RADIATION Large doses of radiation are harmful to living tissue. Radiation can be measured with a Geiger counter – a device that measures radioactivity.

 In nuclear fission, large atoms are split apart to form smaller atoms, releasing energy.  Fission also produces new neutrons when an atom splits. 

Nuclear Fission Reactions The neutrons released can cause a chain reaction with other atoms that are near them. Click here for a chain reaction demo [

Nuclear Fission Reactions In order for a chain reaction to continue, a certain amount of material, known as critical mass, is needed. Click here for a simulation

Nuclear Fusion Reactions Two nuclei of low mass are combined to form a nucleus of larger mass. [ Intermediate
