METHOD FOR MEASUREMENT OF RADIOACTIVE INERTIAL GASES IN ATMOSPHERE AND DEVICE FOR ITS REALISATION Russian patent published in 2009 - IPC G01T1/167 

FIELD: measurement equipment.

SUBSTANCE: invention is related to measurement equipment and may find application for measurement and monitoring of main parameters that characterise condition of atmospheric processes, and also to solve a row of ecological problems (reduced risk of NPP operation and other objects of nuclear fuel cycle and prediction of radiological situation around NPP and at a large distance from it). In order to achieve this result, they perform express measurement directly on site of performed investigation. At the same time they identify concentrations of radioactive inertial gases in atmosphere at the level of low background inertial gases in atmosphere at the level of low background values of these investigated isotopes concentrations. They carry out measurement of radioactive inertial gases in atmosphere with the help of gamma-spectrometric analysis. They define concentrations of inertial gases with the help of spectrometric device. Detector body represents cuvette, where liquefied gases are placed. At the same time investigated air components are previously changed over to liquid state by means of cryogenic method.

EFFECT: expansion of functional resources.
