Establishment of Calibration Curve for Optical Density Measurement Devices for the Two Methods of Development of X-Ray Film by 241Am and Comparison with Theoretical Results

The aim of this study is to find calibration curve for the densitometer that measures the optical density, because of the error associated with the instrument measurements due to the reduction of efficiency because of the instrument ageing. The calibration is done for the instrument when the film is processed manually and automatically. A comparison with the theoretical results is made.
