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><br><i>CERN@school was supported by the UK Science and Technology Facilities Council (STFC) via grant numbers ST/J000256/1 and ST/N00101X/1, as well as a Special Award from the Royal Commission for the Exhibition of 1851.
