Question 50
Easy

A student investigates how the thickness of aluminium sheets affects the transmission of beta radiation.

A diagram showing a radioactive beta source on the left, a Geiger-Müller detector connected to a counter on the right, and an aluminium sheet placed vertically in the gap between them. All components are aligned coaxially along a horizontal line.

Name one variable that must be kept constant in this investigation to ensure valid results.
