More than 3000 radiographs were required to inspect the field welding process for weld integrity. Local state government used SLTL to complete analysis of drinking water from hundreds of cities state wide. Testing of the reentry face shields used by astronauts required special environment conditions. Medical instruments and implant materials have been the subject of mechanical and other testing methods. Three (3) inch thick steel to be used as a launch pad for the Federal space exploration was inspected by radiographic examination before installation. Failure analysis of baseball foul poles which had developed cracks kept our technicians in left field for a while. Ultrasonic examination of bolts used to secure the rails to concrete supports in the mass transit system.
