CERN@school: A simple source - potassium chloride

We present some instructions for making a safe source of beta radiation using potassium chloride (KCl). This can then be used for testing the operation of your CERN@school Timepix detector and doing some basic analysis with the Pixelman particle counting software. Instructions are provided within.<br><br>To find out more about taking part in authentic research with the CERN@school programme, please visit:<br><br>http://researchinschools.org/CERN<br>
