Abstract

The remote analysis capabilities of Laser-Induced Breakdown Spectroscopy (LIBS) as applied to radioactive materials and/or environments has been previously reported (for example, refs. 1, 2). For remote measurement applications, the laser energy and the plasma light may be delivered / collected using either i) optical-fibres or ii) a telescope arrangement and direct line-of-sight between the LIBS instrument and the target material. We report here the development of two novel LIBS-based instruments; one uses a telescope arrangement and can perform measurements over distances of up to 30 metres in air and another which employs optical-fibres and a miniature remote probe head.
