PROCESS OF DISTANT TEST OF MASS CONCENTRATION OF FINELY DISPERSED AEROSOLS OF TOXIC AGENTS BY THEIR INHERENT LUMINESCENCE AT LOCATIONS OF STORAGE AND DESTRUCTION OF TOXIC AGENTS WITH EMERGENCE OF UNUSUAL CONDITIONS

摘要

optical methods of measurement of physical and chemical characteristics of aerosol atmosphere. SUBSTANCE: technical objective of invention lies in development of process of distant test of mass concentration of finely dispersed luminescent aerosols of toxic agents independent of size of aerosol particles against background of unintentional impurities. In correspondence with invention laser sounding with ultraviolet radiation with wave length lambda= 266 nm, recording of background characteristics (Ib) of atmosphere and intensity (Il) of luminescence signals of aerosol of toxic agent in spectrum region 300-440 nm are conducted. Amplitude of luminescence signal is normalized to amplitude of signal of combination of dispersion of nitrogen of air on wave length lambda=284 nm and preliminary calibration of sounding equipment to finely dispersed fraction of aerosol is conducted. Intensity (Id) of signals of backward dispersion at wave length of sounding radiation is recorded to exclude influence of presence of unintentional impurities on results of sounding. EFFECT: enhanced efficiency of process of distant test of mass concentration of finely dispersed aerosols of toxic agents independent of size of their particles. 1 cl, 3 tbl
