MEASURING METHOD OF ACTIVITY OF WATER SOLUTION SAMPLE AS PER Со, AND SYSTEM FOR ITS IMPLEMENTATION Russian patent published in 2015 - IPC G21F9/30 G01T1/178 

FIELD: power industry.

SUBSTANCE: according to a measuring method of activity of a water solution sample of stillage residues as per Co₆₀ after completion of each processing stage of stillage residue and before supply to the next stage a provision is made for check of residual content of ⁶⁰Co, and until it is identified, the next stage will not begin.

EFFECT: possible determination of radioactivity as per ⁶⁰Co provided that its content in the solution is low during chemical treatment of the solution and its filtration, improvement of efficiency and measurement speed, and acceleration of stillage residue processing.
