Episode 511: Absorption Experiments

In this learning episode, from the Institute of Physics, students investigate the absorption of radiation and how this can be illustrated experimentally. The investigations look at sources of alpha and beta radiation. A model, looking at the absorption of light as it passes through successive microscope slides, is used to illustrate the absorption of gamma radiation.

The activities described include:
* absorption of alpha radiation
* range of beta particles in aluminium and lead
* demonstrating the absorption of radiation by living matter
