Abstract:

The potential of a lidar system for monitoring the contamination of atmospheric air with radionuclides of cesium, strontium, xenon, and krypton was evaluated on the basis of differential absorption (DA) and resonance fluorescence to determine the minimum possible concentrations. The obtained results for the solution of the lidar equation show that the lidar system of DA and scattering can be used to determine the concentration of the investigated radionuclides in the atmosphere in the range of 10⁸–10¹⁵ cm⁻³ on a path up to 10 km long at selected wavelengths of laser radiation, which agrees well with previous results for isotopes of iodine. Lidar fluorescent probing of the investigated radionuclides in the atmosphere at selected wavelengths of laser radiation is possible at distances up to 400 m.
