Does Alconox decontaminate stainless steel from radioactive contamination?
Yes, Alconox powder can decontaminate stainless steel of radioactive contamination. The phosphates and chelating agents combined with the wetting agents in Alconox are known to be effective at decontamination.
We recommend use of a warm (if practical, otherwise ambient temperature solutions, it just takes longer) 1% (10 g/L or 1.25 oz/gal) solution of Alconox detergent in water for manual or soak cleaning. Do not use any kind of pressure spray or automated cleaning equipment as Alconox is a high foamer.
Note that Alconox will bind with radioisotopes and will inhibit separation and waste treatment of the spent cleaning solutions by ion exchange columns. It is better to treat spent cleaning solutions by evaporation than by ion exchange. Sometimes it is necessary to use an anti-foamer in the evaporator depending on the evaporator design and the volume of solution being treated with what other types of waste streams if any.
