Leading techniques for radioactive decontamination

In the Argonne Laboratory (Illinois, Usa) are tested the last techniques of reactor decontamination. Two robots are working for two years to decontaminate a reactor that have worked during twenty five years from 1954 to 1979. The aim of this operation is to test the techniques of decontamination that are going to be used in fifty years in 7000 nuclear installations, in Usa. (N.C.)
