Abstract: In order to improve radiation monitoring capabilities around the world, the International Atomic Energy Agency (IAEA) has organized a comparison project of laboratory radioactive surface contamination measurements. According to the requirements of IAEA, we developed a scheme with self-made three layer auxiliary brackets used. The measurement results obtained were evaluated as “ACCEPTABLE” in the IAEA comparison report. Based on the results of this comparison, several issues that should be paid attention to in the measurement of radioactive surface contamination are put forward.

Key words: Radioactive surface contamination, Direct measurement, Support method, Comparison
