METHOD OF DETERMINING THE LOCATION OF A POINT SOURCE OF GAMMA-RADIATION ON TERRAIN Russian patent published in 2019 - IPC G01T1/00 

FIELD: physics.

SUBSTANCE: invention relates to search and detection of ionizing radiation sources and is intended for search of point sources of gamma-radiation. Method of determining location of a point source of gamma-radiation on terrain comprises steps of conducting radiation survey with measurement of dose rate of gamma-radiation, wherein measurements are taken at points lying on a circle with radius R, inside which there is a source, determining points with the smallest P_min and the largest P_max dose rate values, wherein it is considered that the desired source is on the line passing through said points, calculating the distance from the point with the largest P_max value of dose rate to source of gamma radiation by formula

EFFECT: technical result is faster search and reduced dose loads on personnel involved in carrying out works.
