General Advice Values are for reference only. It might be necessary to adjust or modify the above indicate values, depending on the type and brand of the intensifying screen and the x-ray film. If the developed radiographs turned out too light, they are underexposed. If the developed radiographs turned out too dark, they are overexposed. If pictures are too light, increase sec. by one step. If pictures are too dark, decrease sec. by one step. Do not change kV value. Darkroom conditions can also influence the quality of radiographs. Check chemicals and temperature of developer (hand tank 18-20° C – Automatic processor 30-32° C).
* The indicated values are for screens factor 400. However, we recommend utilizing intensifying screen factor 200 or 100! If you choose factor 200 or 100, please adjust the exposure times accordingly!
