The possibilities of early detection of serious accidents at NPPs by using passive microwave radiolocation are discussed. Estimates of the brightness and antenna temperature of a partially ionized cloud created by the first emission of γ-radiation from the Chernobyl NPP are presented. It is shown that the microwave radiation can be detected by means of modern radiometers placed in low-flying satellites and airplanes as well as on stationary ground-based platforms.
