film emulsion is a light-sensitive material. A bar pattern was exposed on single emulsion and double emulsion film with the same eksposi factor that is 50kv, 5mas, and films focus distance of 100cm. processing of the film at the same using a manual process, the results of the study double emulsion films a higher level of sensitivity is low and consequently the value eksposi this film can be used alternating. single emulsion films the sensitivity level is small so eksposi high value and can not be used alternating. movie double emulsions have a higher sensitivity level, the value is low and the radiation dose eksposi Dapa suppressed so that it can be used for general examination.
