INSPECTION OF THICK POLYETHYLENE SECTIONS BY RADIOGRAPHY AND FLUOROSCOPY,

Abstract

A 12 in. x 12 in. x 1 1/2 in. penetrameter was made from high-density polyethylene containing less than 10% amorphous boron. Fourteen other blocks of the same dimensions and material were fabricated; these blocks were void-free. The total thickness of the test specimen was 22 1/2 in. including the penetrameter. A series of tests was run to determine the detectability of various size voids through different thicknesses of material. Test results showed that, using a cobalt-60 source, voids 1/2 in. long x 1/8 in. deep were detectable through the entire 22 1/2 in. of borated polyethylene. In an attempt to use a similar technique as a rapid scanning process, x-ray equipment (150 kv) was teamed with image intensification on a fluoroscopic screen. (Author)
