Easy

A student investigates how the absorption of gamma radiation depends on the thickness of lead.

The apparatus available is:

  • a source of gamma radiation
  • a Geiger–Müller (G-M) tube and counter
  • 8 sheets of lead, each 2.0 mm thick
  • a half-metre rule.

Sketch a labelled diagram showing the correct arrangement of this apparatus when measurements are being taken.
