Coucou @Passllesrep

 

Si on te dit qu'on atténue un faisceau d'un facteur 16 ( 24 ) , ça veut dire qu'on à 4 fois la couche de demi-atténuation ( CDA ) 

Et on te dit que le CDA de ce matériau = 6 mm ( épaisseur de la deuxième lame ) 

Donc la première lame vaut 3 CDA = 3 x 6 = 18 mm soit 1,8cm.

 

C'est plus clair pour toi ? 

 

Bon courage ❤️
