ISO 8690:1988, Decontamination of radioactively contaminated surfaces - Method for testing and assessing the ease of decontamination

Is designed to obtain data allowing the comparison of the ease of decontamination of different surface materials and can be used for comparative tests with any radionuclide in aqueous solution. Comparison is based on the mean residual pulse rates. In order to allow the general qualifications of a surface material as a single product, a method based on contamination by solutions containing Co-60 and Cs-137 is specified. Decontaminability data obtained are not applicable to technical systems.
