Re: Does carbon paper absorb or deflect x-rays?

No, not really.  X-rays are basically gamma rays.  Because of this, you 
normally need something dense to stop them, like a lead sheet.  If there 
were better shielding properties, we wouldn't need lead aprons for 
hospital employees.  It may, however show up on an x-ray film as an 
object.  Although carbon paper may absorb some of the radiation, it's not 
enough to act as a shield.
