Resum

Avui en dia, la contaminació per neutrons en feixos de fotons d'alta energia normalment utilitzats en tractaments radioterapèutics és un problema interessant des del punt de vista de la protecció contra la radiació. Tanmateix, la producció de neutrons quan s'utilitzen feixos d'electrons per a tractar tumors superficials ha estat ignorada. L'objectiu d'aquest treball era estudiar aquesta contaminació i el seu efecte en els pacients. Per fer-ho, es van dur a terme mesures experimentals en un entorn radioterapèutic utilitzant un dispositiu digital sensible als neutrons tèrmics. A més, es va realitzar una simulació Monte Carlo per estimar la diferència de nombre de partícules entre les maneres d'operació amb fotons i electrons necessària per dipositar la mateixa dosi a certa profunditat. Els resultats mostren que la producció de neutrons és menor en els feixos d'electrons que en els de fotons, però no tant com s'havia esperat prèviament.
