Ionizing radiation is widely used in medicine for both therapeutic and diagnostic purposes. In particular, radiotherapy is one of the main cancer treatment strategies used for more than 50% of all cancer patients (over 14 million in ) 1, 2, whilst X-ray based diagnostics account for >65% of all imaging modalities 3 with over 70 million CT scans performed in the US alone .
