METHOD DETERMINING IMPACT OF HARMFUL EFFECTS ON BIOLOGICAL OBJECTS Russian patent published in 2000 - IPC

FIELD: biology, ecology, biological monitoring of degree of impact of harmful effects on biological objects. SUBSTANCE: invention consists in measurement of frequency of vibrations of biological object and in evaluation of degree of impact of harmful effects by it comparison with calibration curve. After measurement of frequency of vibrations of biological object it is subjected in addition to action of alternating electric voltage in range of frequencies close to frequency of vibrations of biological object. Value of additional action is raised by frequency of additional action till effect of synchronization of frequency of vibrations of biological object takes place. Dependence of amplitude of alternating electric action on value of sought-for ( known ) harmful effect is used in the capacity of calibration curve. EFFECT: increased accuracy and authenticity of evaluation of degree of impact of harmful effect on biological objects are achieved thanks to controlled action on biological object and to measurement of parameter changing in wider range. 3 dwg
