Radioavtivity - Penetrative Power of Alpha, Beta and Gamma

Based on Cambridge International O Level Physics, code 5054.
Can be used as part of lesson or as lesson summary after class activity. Teacher can drag and drop paper, Al or Pb into provided slots and observe the change on count rate. Can be use to discuss random activity and penetrative power. Also included is 4 unknown sources which students can use to identify the radiation emitted by using the setup. Teacher can start class discussion based on observation on the drop in countrate to identify the unknown radiations emitted by a source.
