DEVICE FOR SEARCH AND DETECTION OF RADIOACTIVE OBJECTS Russian patent published in 2000 - IPC

FIELD: radar monitoring. SUBSTANCE: invention refers to radar monitoring and can be used for search and detection of radioactive objects on terrain and for spatial distribution of radioactive sources for nuclear-physical logging of wells. Device has primary measurement converters sensitive to radiation field connected to data recording and processing system and placed inside cylindrical collimator correspondingly opposite to first and second groups of channels made in side surface of collimator. Position of channels of first group on sweep is described by position "1" in pseudorandom sequence of N length composed of N+1 units and by position "2" in second group. Collimator is mounted for rotation. Technical result consists in N times increase of angular resolution, in enhanced speed and accuracy of search for radioactive objects, in reduced contribution of noise and background. EFFECT: increased angular resolution, speed and accuracy of search for radioactive objects. 1 dwg
