FIELD: measurement technique.
SUBSTANCE: invention refers to the field of measurement technique and can be used for evaluation of radiation situation in the area of radiationally hazardous enterprises location in conditions of monitored object normal operation and emergency emissions. To achieve result following measurements are taken: measurement of occluded in air gamma-radiation dose power and additional spectrometre measurements of gamma-radiation composition. Herewith, obtained data are used to calculate partial concentrations of radionuclides on underlying surface in pattern of a radioactive cloud or emission plume. Detection device is positioned on light flying machine (FM) which contains dosimetre of occluded in air gamma-radiation dose, laser altimetre and noncontact remote data transmission unit. Spectrum analyser is located on land-based vehicle equipped with measurement data receiver. FM and land-based vehicle contain coordinate measurement units and transceivers for FA flight control, and noncontact remote data transmission unit is connected with outputs of amplitude-digital converter and dosimetre.
EFFECT: measurement sensitivity and accuracy improvement.
