Estimation of the Error of Lidar Measurements of Atmospheric Radionuclide Concentrations

Resumo

The error of measuring atmospheric concentrations of radionuclides cesium, strontium, krypton, and xenon in the 10¹⁰–10¹³ cm^–3 range is estimated. Measurements were taken by differential absorption and scattering lidar with consideration of the laser radiation line width from the lidar composition during probing at distances up to 2 km. For a 25% relative error of measuring the concentration of a radionuclide at wavelength 852.1 nm, the minimum 70 m and maximum 1000 m probing paths for cesium with concentrations of 10¹¹ and 10¹⁰ cm^–3, respectively, were obtained.
