Luminance -The screen luminance required depends on the density of the radiographs. The<br />
following luminance levels are recommended for the perception of information at various levels. The<br />
luminance (or brightness) of the illuminated radiograph shall be not less than:<br />
30 cd/m2 for film densities < 2.5<br />
10 cd/m2 for film densities > 2.5<br />
and wherever possible, approximately 100 cd/m2 or higher. These minimum values require the<br />
following screen luminance’s.<br />
