Abstract

Corrosion hard alpha particle detectors have been fabricated from thin diamond layers grown on silicon using the microwave enhanced chemical vapour deposition technique (CVD). The devices can be directly immersed in radioactive liquid solutions and enable the real time and in situ measurement of their alpha activity. We report here measurements on devices immersed in a plutonium-239 radioactive source diluted in concentrated nitric acid. The tests have shown excellent reliability of the CVD diamond detectors which would be of great benefit in monitoring nuclear fuel assembly reprocessing. We believe that this is the first detection application of CVD diamond which relies on its corrosion hardness. (C) 2000 Elsevier Science S.A. All rights reserved.
