Density vs. Exposure Curves of a Photographic Emulsion for 20∼200 kV Electrons

Density ( D )- Exposure ( E ) curves measured for Fuji Process Orthochromatic plates for electrons with energy 20∼200 kV were given. Dependence of developing conditions on D – E curves was also examined. At a suitable developing condition, D – E curves for electrons with higher energy than 50 kV are linear over a wide range of density, and for electrons with lower energy they bend over at lower density.
