Magnetic extraction of radioactive contaminations from Chernobyl NPP regions

IEEE Transactions on Magnetics, 1992
Preliminary experimental data on decontamination of the soil of a 30-km-zone around the Chernobyl nuclear power plant from radioactive contaminants by dry magnetic separation are presented. The facility used for performing the experiments is briefly described.

Conceptual and Practical Aspects of the Rehabilitation of Chernobyl NPP Exclusion Zone

9th ASME International Conference on Radioactive Waste Management and Environmental Remediation: Volumes 1, 2, and 3, 2003
The problems considered for the substantiation and implementation of a complex rehabilitation territory of the exclusion zone and the zone of absolute resettlement (EZZAR) are directed towards the recovery of its normal economic operation. This process of implementation uses a system of countermeasures. The issues of discussion are normative-legal base,

White clover from the exclusion zone of the Chernobyl NPP: Morphological, biochemical, and genetic characteristics

Journal of Environmental Radioactivity, 2022
A comprehensive study of the biological effects of chronic radiation exposure (8 μGy/h) in populations of white clover (Trifolium repens L.) from the Chernobyl exclusion zone was carried out. White clover is one of the most important pasture legumes, having many agricultural applications.

Characterization of hot particles in surface soil around the Chernobyl NPP

Journal of Radioanalytical and Nuclear Chemistry, 2002
Surface soil samples (0–1 cm) were collected to understand the role of hot particle (HP) in migration of radionuclide approximately 11 years after the Chernobyl accident. Three types of HPs were found by the analyses using alpha-track technique and scanning electron microscopy/energy dispersive X-ray spectrometer (SEM/EDX).

212Pb-Bearing Aerosols in Subreactor Rooms of the Chernobyl NPP Shelter

Radiochemistry, 2019
The results of five-year studies in Shelter subreactor rooms are summarized. At height elevations from 0 to 12 m, the mean volume activity (VA) of 212Pb-bearing aerosols is about 10 Bq m−3. The main source of 220Rn and of its daughter 212Pb is 232Th contained in the building structures. The maximal 212Pb VA is observed in the warm period of a year, and

Assessment of neutron spectral characteristics of the Chernobyl NPP failed reactor

International Journal of Radiation Applications and Instrumentation. Part D. Nuclear Tracks and Radiation Measurements, 1993
Abstract Sets of threshold detectors DNESTR were applied to measure neutron field spectral characteristics in two boreholes of the failed Unit 4 of the Chernobyl NPP. The experimental data were used to calculate the differential neutron spectra. The results obtained show that the shape of the neutron energy spectra is similar to that of the reactor ...

ANALYSIS OF THE CONTENT OF "HOT PARTICLES" IN THE LUNGS AFTER THE ACCIDENT AT THE CHERNOBYL NPP

СИСТЕМНЫЙ АНАЛИЗ И УПРАВЛЕНИЕ В БИОМЕДИЦИНСКИХ СИСТЕМАХ, 2022
Предложена методика гистоавторадиографии для выявления «горячих частиц» (ГЧ) в легких человека и животных, позволяющая не только оценить их локализацию, распределение в легких, связь с гистологическими структурами органа, но и выявить возможные биологические эффекты, связанные с ними. Исследован аутопсийный материал у 3 групп лиц, погибших после аварии

Chernobyl NPP Decommissioning and “Shelter” Object Transformation: Problems of Activity Coordination

Volume 2: Mgmt. Low/Interm. Level Waste; Spent Fuel; Economics/Analyses for Waste Mgmt.; Radiological Characterization/Application Release Criteria; Panel Sessions; Solid Waste Reduction/Treatment; Current Activities in Central/Eastern Europe; Environmental Remediation Technology; LL/ILW; HLW/Spent Fuel; Chernobyl; D&D Waste; Performance Assessment; MOX and Spent UOX; D&D Nuclear Reactors; Decommissioning of Other Nuclear Facilities, 2001
Abstract The shutdown of the last Chernobyl NPP (ChNPP) unit essentially changes situation at the site. The plant terminates the activity as the electricity producer and starts decommissioning of the nuclear installations, located at the site.

Sedimentological study of the Chernobyl NPP site to schematise radionuclide migration conditions

Environmental Geology, 2004
The approach, methods and results of a sedimentological study of a near-surface stratum of Late Pleistocene-Holocene deposits in the near-zone (5–10 km radius) of the Chernobyl Nuclear Power Plant are presented. Sedimentological analyses are carried out at three levels of detail: regional-, local- and object-scale.
