Beryllium has presented problems for nondestructive testing; eddy current and penetrant encounter no particle difficulties, except those inherent in tests themselves; however, radiography and ultrasonics have encountered problems because beryllium is nearly transparent to X-ray, and velocity and sound in beryllium is extremely high; low energy radiography and scintillation counting have eliminated transparency problem; ultrasonic equipment capable of producing high frequency, short-pulse sound waves can cope with high velocity of sound in beryllium; new improved nondestructive techniques and equipment are all capable of meeting standards of production in aircraft and aerospace industry.
