FIELD: measurement technology.
SUBSTANCE: invention relates to the field of radiometric studies and can be used for automated detection of boundaries of radioactive contamination of the area. Essence: an unmanned aerial vehicle is moving along a trajectory, the orthogonal projection of which on the earth's surface coincides with the outer boundary of the detected zone of radioactive contamination of the area. At that, during flight automatic trajectory correction is carried out depending on dose rate of gamma-radiation. Flight trajectory correction is performed by means of automated change of flight course towards increase of dose rate if value of measured dose rate is less than lower limit of preset interval, or towards reduction of dose rate if value of measured dose rate exceeds value of upper boundary of established interval.
EFFECT: high reliability of detecting boundaries of radioactive contamination of the area, providing radiation safety of personnel.
