| abstract in English: | Removal of the long-lived ^{222}Rn daughters (^{210} Pb, ^{210}Bi and ^{210}Po) from copper, stainless steel and germanium surfaces was investigated. As cleaning techniques etching and electro-polishing was applied to samples in a form of discs exposed earlier to a strong radon source. Reduction of the ^{210} Pb activity was tested using a HPGe spectrometer, for ^{210}Bi a beta spectrometer and for ^{210}Po an alpha spectrometer was used. According to the conducted measurements electro-polishing was always more efficient compared to etching and in case of copper the activity reduction factors for ^{210} Pb, ^{210}Bi and ^{210}Po were between 200 and 400. Etching does not remove ^{210}Po from copper but works very efficiently from germanium. Results obtained for ^{210} Pb and ^{210}Bi for etched stainless steel were worse but still slightly better than those achieved for copper. |
