[en] A large volume of radioactively contaminated nickel is being generated from scrap as a result of the Cascade Improvement and Uprating programs of the ERDA gaseous diffusion plants. With appropriate conditions, melting of the scrap reduces the contaminating radioactive isotopes of uranium, ²³⁷Np and ²³⁹Pu below 3 ppM, 1 x 10^-3 ppM and 1 x 10^-5 ppM, respectively. The fission product nuclide, ⁹⁹Tc, is not removed in the melting process. It has been shown that bremsstrahlung produced from beta emissions is a reliable measure of the concentration of ⁹⁹Tc. The lower limit of detection is estimated to be 100 ppb +- 50 ppb with a Ge(Li) detector. A count time of five minutes is sufficient to determine a concentration of 5 ppM +- 1 ppM. It has also been shown that ²³⁵U and ²³⁷Np can be determined to be less than 3.5 ppM and 1 x 10^-3, respectively by gamma spectroscopy techniques in samples containing traces of ⁹⁹Tc
