After a coarse point measurement (11), radioactively contaminated objects (10) are supplied to a fluoro-boric acid bath (12), where they are deposited in a measurable geometry on cathode plates, for example in accordance with an electrolytic process. During the subsequent measurement (13), the metals which are below a predetermined maximum value of the radioactive radiation are separated out and removed for scrap utilisation (14). The materials which are above this limit during the point measurement are first decontaminated (17) and then immersed in the acid bath (12). The fluoro-boric acid is not used up during this process and remains in the system. Boric acid already radioactively contaminated from pressurised water reactors, to which only hydrofluoric acid needs to be added and then distilled can be used for producing the fluoro-boric acid. …<??>The method according to the invention reduces the radioactive waste (16), reduces the instrumentation and administrative expenditure for releasing the non-radioactive materials. …<IMAGE>… |
