Re: Dose to fog camera film

[julian.gibbs@mcmail.vanderbilt.edu]

     Intraoral dental radiographic film, which is direct exposure (i.e., 
     non-screen) film, requires a dose of about 200 mrad to give an optical 
     density of about 1.0.  Photographic film, whose spectral sensitivity 
     should be optimized to visible light rather than diagnostic-energy x 
     ray, might be a little less sensitive to ionizing radiation.
