| description | The invention relates to the field of radiation monitoring, specifically to a method for carrying out a search for and detection of gamma radiation sources. A method for searching for and detecting gamma radiation sources in conditions of nonuniform radioactive contamination additionally comprises stages in which a source of maximally active radiation is determined, the radiation power is measured with a collimated detector and at the same time the distance to the source is determined with the aid of a laser detector rangefinder, readings of the laser rangefinder and the value of a dose rate established by the detector are recorded, and, on the basis of the data produced, the dose rate of the radiation of the actual source is calculated, after which, in order to verify the distance measured to the radiation source, the aiming axis of the rangefinder is moved for a distance horizontally, the measurement is repeated and the distance recorded, the results of successive measurements of the distance are compared and, in the event of a divergence in the measurements within the laser rangefinder error limits, the information is acknowledged as reliable. The technical result consists in increasing the accuracy of measuring a distance to a gamma radiation source. |
