A method of detecting the presence of radioactive waste material (11) on the surface of a storage drum (10), wherein Laser Induced Breakdown Spectroscopy techniques are used to obtain electronic emission spectra characteristic of the waste material (11) where this is present on the surface of the drum (10). Because electronic emission spectra are not affected by the strong background nuclear radiation from the waste material contained within the drum (10), a much improved accuracy of detection is achieved. |
