Detergent designed especially for decontamination of objects contaminated with radioactivity

The detergent shows increased decontamination efficiency and low frothiness at high temperatures. It contains 5 to 60 wt.% of a mixture of non-ionogenous and chelate-forming surfactants of a weight ratio of 4:1 to 50:1, e.g., substituted fatty alcohol with 3 to 20 oxyethylene groups and/or substituted alkylphenols, and alkylamide of an aminopolycarboxylic acid. The remaining volume to form 100 wt.% consists of a mixture containing at least one compound of the condensed phosphate group, a compound of the type of alkaline on neutral reacting simple electrolytes, a compound of the type of organic complexones or their salts, natural or synthetic zeolite, an optical brightening agent, an antiredeposition additive, and a whitening agent.
