RADIOGRAPHY USING DIRECT PRINT RECORDING OSCILLOGRAPH PAPERS

DIRECT PRINT RECORDING OSCILLOGRAPH PAPER HAS BEEN EVALUATED OVER AN X-RAY ENERGY RANGE FROM 50 TO 275 KVCP TO DETERMINE ITS POTENTIAL AS A REPLACEMENT FOR X-RAY FILM IN CERTAIN APPLICATIONS. TECHNIQUE CURVES HAVE BEEN DETERMINED OVER THIS ENERGY RANGE FOR THREE MATERIALS: ALUMINUM, MAGNESIUM, AND TITANIUM. RESOLUTION HAS BEEN MEASURED FOR ALUMINUM AND MAGNESIUM USING PENETRAMETERS. THE DATA OBTAINED MAY BE USED TO ESTABLISH OPTIMUM EXPOSURE CONDITIONS FOR LOCATING HIGH CONTRAST OBJECTS IN AIRCRAFT STRUCTURES. THIS INCLUDES WATER ENTRAPPED IN HONEYCOMB, AIRCRAFT CABLES, AND HYDRAULIC LINES, AND HIDDEN FOREIGN OBJECTS. THE USE OF THESE PAPERS FOR THESE APPLICATIONS WOULD ELIMINATE THE NEED FOR COSTLY X-RAY FILM. IN ADDITION, THE PAPERS CAN BE DEVELOPED BY AMBIENT ROOM LIGHT OR SUNLIGHT, THEREBY CONTRIBUTING TO FURTHER COST REDUCTION BY ELIMINATING THE CHEMICAL DEVELOPING AND HANDLING PROCESS. /AUTHOR/
