A remote sensing method of monitoring heightened soil radioactivity using an onboard radiometer that records indirect effects in the environment is examined. The gamma-spectrometric field surveying was used to determine the soil content of uranium, thorium, and potassium in southeastern Tomsk. Heightened uranium content was found in soil samples fr...

Citing Beloyarsk nuclear power plant (Russia) as an example, the problem of remote detection of radioactivity in the atmospheric pollution is examined. The comparative analysis of injected radionuclides into the atmosphere from the nuclear power plant with advanced fast neutron reactor is carried out. The main radionuclides throw out into the atmos...

The paper states limited availability of the use of the automated radiation situation monitoring system and proposes radiometric complex as more reliable system in the case of an accidental release of the Siberian Chemical Enterprises.

The paper performs the distribution mapping of ion formation intensity based on the contamination map around Fukushima Daiichi Nuclear Power Plant (FDNPP). The study compares the ion formation intensity in soil after Fukushima and Chernobyl nuclear accidents.

A radiation power of an emission plume from the Radiochemical Plant (RCP) of the Siberian Chemical Combine, as an example, was theoretically calculated at 1420 and 1665–1667 MHz. Experimental and theoretical data on the radiation power of an RCP plume were compared, as well as radiation powers of plumes from RCP and the nuclear power plant (NPP).

The calculation of radiation power at 1420 and 1665–1667 MHz frequencies from emission plume for the radiochemical plant of Siberian Chemical Enterprise were performed. The comparison between experimental and theoretical data on radiation power from emission plume of radiochemical plant were drown. Radiation power from emission plume matching perfo...

Detailed analysis of accidental released of radioactive material from Fukushima Daiichi nuclear power plant has shown that long-lived radionuclides add considerable support for intensity of ion formation. Based on the results of airborne monitoring by MEXT and DOE (total surface deposition of Cs134 and Cs137 inside 80 km zone of Fukushima Daiichi N...

The Fukushima nuclear accident showed the importance of timely monitoring and detection of radioactive emissions released from enterprises of the nuclear fuel cycle. Nuclear power plants (NPP) working continuously are a stationary source of gas-aerosol emissions which presented in a ground surface layer persistently. Following radioactive emission,...

Detailed analysis of emergency emission of radioactive material from Fukushima Daiichi nuclear power plant has shown that long-lived radionuclides considerably contribute to the intensity of ion formation. The evaluation technique, used after Chernobyl disaster, allows to make the analysis of intensity of ion formation in the area of Fukushima Daii...

The new diagnostic method of the influence of SHF (superhigh frequency) radiation on the atmosphere at heights 20 - 30 km is considered. By the example of AIR (artificial ionization region) make by the focused nanosecond SHF pulses the process of atomic hydrogen generation is considered. The atomic hydrogen radiation at frequency of 1420 MHz is use...

The problem of remote detecting of a radioactivity in emissions from atomic power stations (APS) is devoted. The basic radionuclides contained in emissions of nuclear energy stations with various types of reactors have been analyzed. The total power spectrum of electrons is determined taking into account their multiplication. Physical and chemical...

The paper describes a passive method of determining the radioactivity level in the emission plumes of atomic power plants (APP) by the secondary emission of radiation from the plume. The emissions have been analyzed from the APPs that exploit the most common types of reactors, and the main beta-radionuclides involved in the emission have been deter...

Physical and chemical properties of the atmospheric components change under action of radioactive emissions, and, as a result, anomalous gas-aerosol and ionized areas are occurred and can be registered by remote optical and radiometric methods. One of the effects, in the view of passive detection of radioactive pollution is the dissociation of wate...
