“…It may not be possible to produce a suitable isotope in these materials by direct activation. TLA technique can be applied in such cases by introducing a suitable isotope from a secondary target by the recoil implantation technique [21][22][23][24][25][26][27]. These materials may change their characteristic properties by direct activation due to generation of local heat during irradiation.…”

“…Even though the implanted activity (∼ 100 Bq) is small it may be enough, compared to background activity (≤ 0.005 cps) in a typical HPGe detector (relative efficiency 30%), to apply the TLA technique to measure the surface loss of materials in the nanometer range with high sensitivity. Several applications of TLA technique have been reported where an ultra thin layer of activity was introduced into polymeric materials through implantation technique [20,23,25,27].…”

Thin layer activation (TLA) technique is a powerful nuclear technique based on the production of a radioisotope in the surface of a material by a charged particle induced nuclear reaction, followed by an estimation of the loss of the activity which is a measure of the surface loss of materials in the range of nanometer to hundreds of micrometer in the fields of wear, corrosion or erosion. The technique has been found to be a very useful tool in the basic scientific research and industrial applications. The present review describes the basic principle of TLA technique, its characteristic features, methodology, scope, applications and various recent developments regarding its growing use. Some of our earlier TLA work carried out with α and heavy ion ( 16 O) in various applied areas is also included here. Heavy ions were used because no other light ions (particularly protons) were available at our cyclotron.
