Abstract
Described are a process and an apparatus for the remote measurement of uranium or plutonium in radioactive materials. in which the sample of the material to be analyzed is to be handled as little as possible. To attain that object it is proposed that the laser beam of a laser is focussed by means of a focussing unit onto the sample to be analyzed, so that a light-emitting plasma is generated, an image of the emission spectrum of the plasma is formed in a spectrograph by means of an imaging unit, and finally it is analyzed by means of an analyzing unit.
Claims2
A process for the remote measurement of uranium or plutonium in radioactive materials characterized by the following steps:
- generating a light-emitting plasma of a sample to be analyzed by means of a laser beam,
- forming an emission spectrum of the plasma in a spectrograph,
- flushing the plasma with dust-free air for the purpose of shielding the plasma from disturbance effects due to the ambient air during the forming of the emission spectrum,
- and analyzing the emission spectrum.
