“…The Quattro Pro' macro was qualified by noting that the results displayed were consistent with the counts reported by GammaVision4. Documentation resides in contdled laboratory notebooks (Greenwell et al 1992, andDOE 1994). The GammaVisionM software was qualified by noting the consistent energy accuracy of the gamma spectrum.…”

“…Efforts are underway to produce a single integrated remote analytical system capable of collecting both isotopic and chemical information. Principal methods being investigated to augment the existing nuclear probe are various forms of fiber optic spectroscopy (Greenwell et al 1992). Raman, Fourier transform infrared (FlTR), fluorescence, time resolved laser-induced fluorescence (TRLIF), laser-induced breakdown spectroscopy (JABS) and laser ablation mass spectroscopy (LA-MS) are presently being investigated for use.…”

The aim of this work is to illustrate the activities related to the assessment of fibre-optic technology in hostile nuclear environment and to provide the interested reader with an introduction to this subject. Potential applications of fibre-optics in nuclear installations are summarised. Effects of nuclear radiation on optical fibres are shortly discussed. The absence of complete predictive models for the radiation induced attenuation in optical fibres is illustrated by modelling attempts and explained by the wide range of parameters which influence the induced loss. The need for standards in assessing the fibre's radiation resistance is also presented. Finally, experimental methods are illustrated with results of radiation induced attenuation in optical fibres obtained for a high-dose rate and high total dose irradiation, as not often reported in literature.( *) This paper was presented at a poster session.

Scintillator Light Source for Chemical Sensing in the Near-Ultraviolet

1997

A novel chemical sensor based on a light source composed of a radionuclide and a scintillator is experimentally evaluated. Proper selection of a radionuclide/scintillator combination permits fabrication of a practical light source emitting in the ultraviolet (UV). Such a UV light source is critical for chemical sensors which utilize UV-excitable chromophores or fluorophores. Unlike conventional gas-filled discharge lamps, the developed UV source is compact, inexpensive, simple in design, stable, and highly reliable, and it does not require an external power source. The utility of the new source was demonstrated through construction of sensors for oxygen. This application was selected for experimental evaluation of the new light source since oxygen sensors have been characterized well with conventional light sources. Although the scintillator light source is less intense than conventional sources, its excellent short- and long-term stability provides a reproducibility of fluorescence measurements of about 0.35% RSD. The stability of the scintillator light source suggests its utility in simple single-beam detection configurations.
