          Abstract

          RESUMEN El trabajo presenta los resultados del Análisis Probabilista de Seguridad al proceso de tratamiento de radioterapia con un acelerador lineal de uso médico desarrollado por el Foro Iberoamericano de Organismos Reguladores Radiológicos y Nucleares. Se evaluaron las exposiciones accidentales potenciales durante el proceso de tratamiento del paciente, los trabajadores y miembros del público, aunque el énfasis del estudio se orientó hacia los pacientes. El método de análisis de modos de fallos y efectos se utilizó para definir los sucesos iniciadores de accidentes y los métodos de árboles de sucesos y árboles de fallo para determinar las secuencias accidentales que se pueden producir. Una vez cuantificada la frecuencia de ocurrencia de las secuencias accidentales se realizaron análisis de importancia para determinar los sucesos más significativos desde el punto de vista de la seguridad y se identificaron los principales contribuyentes al riesgo, así como las recomendaciones de seguridad más apropiadas para reducirlo.

          ABSTRACT This paper presents the results of the Probabilistic Safety Assessment to the radiotherapy treatment with an Electron Linear Accelerator for Medical Use, which was conducted in the framework of the Iberian-American Forum of Radiological and Nuclear Regulatory Agencies. Potential accidental exposures during the treatment of patients, workers and members of the public were assessed, although the study was mainly focused on patients. The methodology of failure modes and effects analysis was used to define accident initiating events and methods of event tree and fault tree analysis to determine the accident sequences that may occur. After quantifying the frequency of occurrence of the accident sequences, an important analysis was carried out in order to determine the most significant events from the point of view of safety. The major contributors to risk were identified as well as the most appropriate safety recommendations to reduce it.
