PROCESS OF REGISTRATION OF AIR RADIOACTIVE EJECTION BY OPTICAL FLUORESCENCE Russian patent published in 1999 - IPC

FIELD: environmental control. SUBSTANCE: process of registration of air radioactive ejection by optical fluorescence of air is based on measurement of intensity of optical radiation of this ejection by photometric plant on which optical axis there are placed in time sequence three optical filters in " working " regions of spectrum: 400-420 nm, 430-450 nm, 460-480 nm and filters having bandwidth outside mentioned " working " regions which readings are subtracted from readings of photometric plant in " working " regions. EFFECT: increased accuracy and reliability of identification of air radioactive ejection of object under technological or emergency condition, including cases of atomic explosion and catastrophes. 2 cl
