Question 23

A radioactive source is placed in front of a Geiger-Müller (GM) tube detector as shown in the diagram. Various absorber materials are positioned between the source and the detector to identify the nature of the emitted radiation. The table shows the corrected count rates recorded for each absorber.

Experimental setup and results table

Which types of radiation are being emitted by the source?

$α\alpha$ and $γ\gamma$ only

$β\beta$ and $γ\gamma$ only

$α\alpha$ and $β\beta$ only

$α\alpha$ , $β\beta$ and $γ\gamma$
