When a sufficient number of visible lig...

When a sufficient number of visible light photons strike a piece of photographic film, the film becomes exposed. An X-ray photon is more energetic than a visible light photon. Yet, most photographic films are not exposed by the X-ray machines used at airport security check points. Explain what these observations imply about the number of photons emitted by the X-ray machines.
