A method for cleaning radioactive liquids, comprising the steps of:

• providing radioactive liquid to be cleaned in a reactor,
• adding a preparation for cleaning radioactive liquids into the reactor, the preparation produced by a method for the production of a perparation for cleaning radioactive liquids and surfaces comprising
• providing of a substance with aerobic microorganisms, particularly cultivated comprising the steps of:
• providing an aqueous solution having a pH value of 5.5 to 9.0 in a container
• adding a substrate in a first substrate dosage to the aqueous solution,
• adding further elements to the aqueous solution,
• adding an inoculant with microorganisms to the aqueous solution,
• wherein an initial product is provided by the abovementioned steps, and wherein, subsequently, the following steps are performed:
• introducing air into the initial product or into intermediate products developing therefrom,
• varying a termperature of the initial product or the intermediate products developing therefrom in a range from 15 to 35 degrees Celsuis,
• wherein, after having added the substratae in the first substrate dosage, the following steps are performed for monitoring the cultivation:
• taking a reference liquid sample and determining a first concentration of organic substance in the reference liquid sample, substance in the reference liquid sample,
• taking another liquid sample and determining another concentration of organic substance in the further liquid sample after the expiration of the first waiting time,
• if the further concentration of organic substance is smaller than 10 percent of the first concentration of organic susbtance, adding substrate in another substrate dosage,
• repeating the abovementioned steps for monitoring the cultivation until a sufficient amount of biomass is present in the container, or
• providing of a substance with anaerobic microorganisms, particularly cultivated the anaerobic cultivation of microorganisms comprising the steps of:
• providing an aqueous solution having a pH value of 4.5 to 7.5 in a container,
• adding a substrate in a first substrate dosage to the aqueous solution,
• adding further elements to the aqueous solution,
• adding an inoculant with microorganisms to the aqueous solution, wherein an initial product is provided by the abovementioned steps, and wherein, susbsequently, the following steps are performed:
• hermetically sealing the container,
• varying a temperature of the initial product or the intermediate products developing therefrom in a range from 40 to 80° C.,
