Abstract: The invention relates to nuclear technology, namely to decontamination of radioactively contaminated metals. The cleaning composition consists of: nitric acid (15.0~25.0%), sulfamic acid (0.1~4.0%), hydrofluoric acid (0.5~2.0%) and water (the rest). The method allows to implement monobath method of decontamination, in low temperature, which greatly simplifies the technical process, and it reduces the quantity of liquid waste by conducting effective decontamination.
