Abstract: Based on the analysis of testing principles, technical characteristics and surface suitability of various testing methods for removal effect of radioactive contamination, atesting method suitable for removing dust on concrete surface is proposed. The key control factors which influence the testing results have been identified and studied. The influences of detergent dosage, dust dosage and other experimental factors on removal effect are revealed, and some reasonable control principles and methods of experimental factors are obtained. This study may effectively improve the scientific nature, repeatability and reliability of testing methods for evaluating removal effect of radioactive contamination on concrete surface.

Key words: surface contamination, removal effect, testing method, concrete surface
