Radioactive Decontamination Technique Used in Decommissioning of Nuclear Facilities

摘要

The decontamination of equipment and nuclear installations is a concern from many points of view. The method adopted can minimize the radioactive waste, preventing the environmental pollution and optimizing the environmental protection. For this purpose a research study was developed to evaluate the efficiency of two products, solutions for chemical and radioactive clean-up recently introduced to the market. The ability of the agent to remove the contamination was tested for five types of materials. The objective of the study was to evaluate the deftness of the solutions to remove the contamination with 137 Cs and 60 Co. The results were quantitative by evaluated using the percent of contamination removal by gamma-ray spectrometry.
