Abstract (en)

[origin: EP0557914A2] In asbestos clean-up operations in nuclear plants or in plants which are exposed to above-average radioactive radiation, measurements for determining the radioactive contamination of the material to be removed must be carried out before hazardous asbestos-containing substances are removed. These measurements can be carried out more simply and at less risk if samples of the hazardous asbestos-containing substance are liquefied by decomposition, particularly using hydrofluoric acid.
