Estimation of the Error of Lidar Measurements of Atmospheric Radionuclide Concentrations

摘要

The error of measuring atmospheric concentrations of radionuclides cesium, strontium, krypton, and xenon in the 10(10)-10(13) 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 10(11) and 10(10) cm(-3), respectively, were obtained.
