The purpose of this document is to provide an introduction and overview of methods of performance qualification (PQ) dose mapping of medical products that are sterilized by ionising radiation. It is based around the requirements found in ISO 11137-1 (ISO 2006), but is written in a narrative style to give a tutorial approach. In this respect, it differs from more formal guidance documents, such as those produced by ISO (e.g. ISO 11137-3 & 4) (ISO 2017, ISO 2020) and ASTM (e.g. ISO ASTM 52303, 2013), although it is entirely consistent with those documents.
