The main activities of the department:
Solving environmental and energy problems by radiation-chemical methods
The main scientific results of the department:
The effect of temperature, absorbed dose and dose rate, as well as the shape and material of the reaction vessel on the formation of high molecular olefins and gases in radiation-thermal transformations of oil and oil fractions under the influence of gamma, neutron-gamma and accelerated electrons has been studied. The kinetics and mechanism of obtaining hydrogen and synthesis gas from oil residues, oil-bitumen rocks and solid organic fuels have been investigated, and the optimal values of the parameters have been determined. Radiation-chemical transformations of oil, tar and asphaltene oil fractions have been studied, and regularities of degradation of these fractions in the environment have been examined. The transformation of polycyclic aromatic hydrocarbons of oil under the influence of environmental factors has been researched. Methods of radiation-thermal neutralization of waste and oil-containing waters formed during oil transportation have been developed. Radiation-chemical transformations of composite materials obtained from petroleum bitumen have been studied and the ways of increasing their radiation resistance have been shown.

The main activities of the Laboratory:
Study of the effect of ionizing radiation on dielectric and electrical relaxation, impedance spectrum and phase transitions in crystals and solid solutions such as TlInS2 and TlGaSe2.
The main scientific results of the Laboratory:
1. It has been determined that TlGaSe2 crystal has anomalies in temperature dependences of dielectric permittivity and loss- angle tangent at temperatures above 300K (paraelectric phase). (T = 415 K and T = 532 K)
2. The complex impedance and complex dielectric spectrum of the TlGaSe2 (Z٭(f)) crystal have been studied in the temperature range 100–550 K and frequencies 102–106 Hz. It has been shown that the TlGaSe2 crystal has ion conductivity in the 415 K ÷ 532 K temperature range. The equivalent circuit substitution method (Z″−Z′) has been used to analyze complex planar diagrams and determine the frequency domain boundary for each temperature.
3. It has been established that the boundary of the high-frequency region on the complex planar diagram (Z″–Z′) of a TlGaSe2 crystal irradiated with γ-quanta at a dose of 20 Mrad shifts towards decreasing frequency, and two gadogrammas are observed on the complex planar diagrams (Z″–Z′). The mechanism of conductivity has been determined both in the irradiated and non-irradiated TlGaSe2 crystals (electron and at high temperatures – ion). Type of polarization: electron and ion-relaxation polarization.

The main activities of the Laboratory:
- Implementation of studies on the distribution of Uranium-Thorium-Radium isotopes in water and soil ecosystems of Azerbaijan and related heavy metals and polycyclic compounds in ecologically sensitive zones and preparation of databases;
- Study of environmental contamination with radionuclides, heavy metals, toxic elements and common organic hydrocarbons in oil production areas;
- Study of radionuclides, metals and organic pollutants in the waters and bottom sediments of the Azerbaijani sector of the Caspian Sea;
- Study of natural and anthropogenic pollutants in the river basins of Azerbaijan and the risks they cause;
- Investigation of the effect of stressors on biological objects in the environment.
The main scientific results of the Laboratory:
1. The content of radionuclides, heavy metals, toxic elements and the total content of organic hydrocarbons in oil-producing and related areas were assessed and hotspots were identified in the areas under study. The age of oil reservoirs formed by formation waters was determined using the activities determined for Ra228 and Ra226 isotopes.
2. In the Azerbaijani sector of the Caspian Sea, radionuclides, metals and organic pollutants were studied in the water and bottom sediments and based on the results, Geoaccumulation Index (Igeo.), Contamination Factor (CF), Enrichment Factor (EF), Environmental Risk Factor (Er), Degree of Contamination ( DC), Pollution Load Index (PLI), Environmental Risk Index (RI) were calculated. Despite anthropogenic enrichment and moderate contamination of the study area, the potential environmental risk was low.
3. Samples of water, bottom sediments and soil taken along the transboundary rivers were examined to determine the concentration of radionuclides, heavy metals and pesticides and the risks associated with them were assessed. It has been determined that changes in water quality due to natural and anthropogenic effects and seasonal changes may increase radionuclide and heavy metal accumulation. As a result of the study of pesticides in transboundary river ecosystems, it was found that there are more DDT and its isomers, a-BHQ, b-BHQ, d-BHQ, dieldrin, endosulfan II and isomers of endosulfan sulfate at the sites.
4. Water and bottom sediments taken from the Northern rivers of Azerbaijan and the rivers located on the southern slope of the Greater Caucasus, and soil samples taken from the surrounding areas were studied for radionuclides and elemental composition, and the degree of contamination was determined. The water quality was assessed for these rivers.
5. Contamination of natural and anthropogenic origin and associated risks were assessed in the ecosystems of the rivers of the Lesser Caucasus. Based on the research results and calculated data, the influence of natural and anthropogenic changes in river basins on water quality has been examined.
6. Initial assessment of the radioecological situation and radiation background measurements were carried out in the liberated territories. As a result of the study of water sources in the area, it was found that the concentration in Okchuchay, which enters the Zangilan region of Azerbaijan from the territory of the Republic of Armenia, is 1.7-1.8 times higher than the permissible limit values for Mn, 3.1-3.6 times for Al, and 6-7.5 times for Fe. Pesticides were evaluated in arable soils and the concentrations of prohibited DDT and its isomers were determined to be superior to other components.
7. Paramagnetic centers in biological objects were studied and it was found that various stressors (temperature, humidity, radiation, etc.) cause their magnetic properties.
8. A microplastic assessment methodology was established in accordance with the NUTEC protocol, enabling the first comprehensive analysis of microplastics in environmental samples collected from the Azerbaijani sector of the Caspian Sea. The findings revealed a markedly higher concentration of microplastic contamination at Shikhov Beach relative to Novkhani Beach.
