Key Info
  • Alpha, beta and gamma radiation (pt 1/2)
  • Duration: 00:56
  • Properties of alpha, beta and gamma radiation are demonstrated. Alpha radiation does not travel far in air and can be stopped by a thin sheet of paper. Beta radiation is more penetrating but finds it more difficult to pass through denser materials. Gamma radiation is the most penetrating of the three and only very dense materials such as lead will greatly reduce gamma rays.
