DEKONTAMINERANDE REAGENS FOR RADIOAKTIVA SYSTEM SAMT SETT ATT DEKONTAMINERA EN KERNREAKTOR ELLER DESS KOMPONENTER

摘要

Surfaces contaminated with radioactive materials can be decontaminated by circulating an aqueous solution of decontaminating reagents which comprises organic acid decontaminating agents usually including oxalic acid, and formic acid, in contact therewith. The reagent preferably comprises both citric acid and EDTA in addition to oxalic and formic acids. It has been found that the efficacy of these organic acid decontaminating reagents can be prolonged under ionizing radiation by the inclusion of formic acid therein.
