BETA-RAY BACKSCATTERING GAGE FOR MEASURING PAINT FILM THICKNESS

AN EXPERIMENTAL NONDESTRUCTIVE PAINT THICKNESS GAGE USING THE BACKSCATTERED BETA RADIATION FROM SR-Y-90 HAS BEEN DEVELOPED BY THE NAVAL CIVIL ENGINEERING LABORATORY. THIS GAGE WILL MEASURE A VARIETY OF COMMONLY USED PAINTS HAVING THICKNESSES RANGING FROM 0.5 TO ABOUT 30 MILS ON WOOD WITH AN ERROR OF APPROXIMATELY PLUS OR MINUS 0.5 MIL. GRAPHS ARE GIVEN DEMONSTRATING THE PERFORMANCE OF THIS GAGE IN MEASURING THE THICKNESS OF FILMS OF VARIOUS FEDERAL SPECIFICATION PAINTS (TT-P-102, TT-P-0055A, TT-E-489) AND PAINT A, A PROPRIETARY PAINT. /AUTHOR/
