MARRTA: Risk matrix in advanced radiotherapy.

Purpose: Proactive risk analyses identify potential risks before they occur, enabling us to pinpoint the most vulnerable aspects of our treatment process, thus promoting safer treatments. The proactive risk matrix methodology assesses the risk from potential errors and failures (initiating events) by evaluating and integrating their frequency, the severity of their potential consequences and the probability of failure of the barriers designed to prevent these consequences. Based on this methodology, the MARRTA project derived a theoretical risk model of advanced radiotherapy treatments and developed software to implement the model and facilitate the risk analysis.

Synthesis of the European ALARA network 20th workshop 'ALARA for interventional radiology and nuclear medicine'.

The European as low as reasonably achievable(ALARA) network regularly organises workshops on topical issues in radiation protection (RP). The topic of the 20th workshop was: 'ALARA for interventional radiology (IR) and nuclear medicine (NM)'. The objective was to examine the challenges faced when applying the optimisation principle (ALARA) in IR and NM and to consider how ALARA could be better implemented for patient and staff exposures.
