Slt !

 

je comprend pas trop bien  la justification de cet item qui est faux :

 

"Si la source avait été des photons de 511keV provenant de l’annihilation du 18F, le nombre de photons par seconde arrêtés par la hotte et le tablier serait identique."

Faux. La CDA dépend de l’énergie du rayonnement .
