MEASURING METHOD OF ACTIVITY OF THE WASHING AGENTS AT TREATMENT OF THE ANIMALS LEATHER AND-OR THE ANIMALS WOOL POLLUTED BY THE RADIONUCLIDES Russian patent published in 2007 - IPC G01N31/00 G01N13/00 G21F9/00 A61L2/18 

FIELD: radiation ecology; chemical industry; light industry; measuring methods of activity of the washing agents at the treatment of the animals leather and-or the animals wool polluted by the radionuclides.

SUBSTANCE: the invention is pertaining to the field of radiation ecology, in particular, to the measuring method of activity of the washing agents intended for treatment of the animals leather or the animals wool polluted by radioactive particles by means of the safe simulators of the radioactive impurities for the purpose of production out of them of pollution-free raw for the light industry. The measuring method of the animals leather and-or the animals wool polluted by the radionuclides consists in determination of the pollution intensity of the washing solution by the known procedures with the further calculation of the washing means activity and at that using the solid inorganic particles. In the capacity the solid inorganic particles use the polydispersed particles of the reduce iron powder, which makes the role of the simulator of the radioactive particles located on the leather and-or the wool of the animals. After application of the simulator the leather or the wool of the animals is treated with the different washing agents, then - take-off of the particles of the reduced iron powder from the washing agents exercise by means of the cylindrical form magnet disposed in the chemical test tube with the following analysis of the measuring results and evaluation of the washing agents effectiveness for decontamination of the animals in compliance with the formulas: De=[(M_a-M_c)/M_a]·100% and D_r=M_a/M_c , where: D_e - effectiveness of the decontamination in percents; D_r - repetition of the decontamination; M_a - the mass of the applied simulator, mg/dm²; M_c - mass of the simulator collected after washing, mg/dm² . The invention allows to improve the ecological security of the raw for the light industry, and also to increase reliability and to simplify the procedure of measuring activity of the washing and decontamination agents.

EFFECT: the invention ensures the improved ecological security of the raw for the light industry, the increased reliability and simplification of the procedure of measuring of activity of the washing and decontamination agents.
