Question 53
Easy

A researcher investigates how the attenuation of beta radiation is affected by the thickness of shielding material.

The apparatus available is:

  • a sealed strontium-90 source (emitting beta radiation)
  • a Geiger–Müller (G-M) tube connected to a digital counter
  • 6 sheets of aluminium, each of thickness 0.5 mm
  • a metre rule.

Sketch a labelled diagram showing the experimental setup that should be used to obtain measurements for this investigation.
