Abstract
The thin layer activation (TLA) technique was applied to study the surface erosion of zircaloy clad material during laser ablation process by producing a suitable γ-ray emitting radioisotope in the clad surface using 40 MeV α-particles. This paper reports the rate of surface erosion of zircaloy as a function of deposited laser energy in the range of a few hundred of millijoules to a few kilojoule. The minimum detection limit was found to be 80 ± 25 nm in the measurement of surface loss of material due to laser exposure by TLA technique.
