* [http://www.hep.ucl.ac.uk/pbt/wikiData/presentations/2017/LK20170322_ProtonBuildUp.pdf Looking at dose build-up effect in proton therapy].&lt;br /&gt;
** Dose increases at start of X-ray depth dose curve due to short-range electron shower.&lt;br /&gt;
** Effect present for protons but much smaller.&lt;br /&gt;
* Managed to reproduce results over 10mm from Benjamin Tham&amp;#039;s previous simulations.&lt;br /&gt;
* Build-up effect present for both electrons and secondary hadrons, but build-up much shorter for electron shower (~1mm).&lt;br /&gt;
* Will run simulations for 100MeV and 200MeV with higher statistics.&lt;/div&gt;</summary>
