Thin layer activation (TLA) for industrial wear measurements

Thin layer activation (TLA) is a technique in which a small area of a component subject to erosion, wear or corrosion is made slightly radioactive using a nuclear accelerator. As wear of the activated area occurs the amount of radioactivity decreases proportionately. The chosen radioactive species (eg cobalt-56) should decay by emitting gamma rays, which can be detected online and remotely even through a wall, without any contact with the irradiated area. The detector can be up to 2 m away, and state of the art analysis equipment is used. The technique has been used in laboratories for many years, but this project has addressed the technical, licensing and human factors associated with using the technique in an industrial plant, in power plant boilers.
