FIELD: radiation monitoring technique. SUBSTANCE: radar systems are used for probing plasma-forming area (plasmoids) associated with radiation and reflection factor о is measured by echo signal. Following parameters of atmosphere are also measured: relative humidity D, pressure P, temperature T, and air (convective) flow velocity U0. Measurement results are used to find emission power Pl for monitored area polluted with radioactive emissions and surface density of activity q0 for same area from correlative equations. Radiation characteristics found in this way serve as indications of radiation situation in area being monitored. EFFECT: provision for remote radiation monitoring without mounting sensors in polluted environment. 2 cl, 4 dwg
