The increase on the collective radiation dose due to the large number of medical imaging exams has led the medical physics community to deeply consider the amount of dose delivered to patients as well as its associated risks in these exams. For this purpose we have developed a Monte Carlo tool, PENRADIO, based on a modified version of the 2006 release of the PENELOPE code, to obtain an accurate individualized radiation dose in conventional and interventional radiography and in computed tomography (CT). This tool has been validated showing excellent agreement between the measured and simulated organ doses in the case of a hip conventional radiography and a coronography. We expect the same accuracy in further results for other localizations and in CT examinations.
