Properties of Radiation

The three videos below feature demonstrations of the properties of the radiation emitted from three different sources: Plutonium-239; Strontium-90; Radium-226.
The first video demonstrates the range of the three radiations in air.
The second video demonstrates the penetration of radiation from each of the sources through different materials: Tissue paper, Aluminium and Lead.
The final video is a compilation of the above two.
