qualcuno sà risolvermi il seguente esercizio di radioprotezione?? Su un assorbitore in Al di spessore di massa pari a 20 g/cm 2 incide una fluenza di 1000 fotoni/cm 2. Il fascio è monocromatico, ad energia 500 keV. Si facciano le seguenti ipotesi semplificative: i secondari sono generati con uno spettro equivalente a quello di un emettitore beta con E max =500keV ; si trascura la possibilità che i secondari fuoriescano dall’assorbitore; i fotoni generati all’interno dell’assorbitore fuoriescono tutti. Stimare il KERMA e la dose assorbita.
