AB  - Mushroom cultivation and consumption have been steadily increasing in recent decades, however, after mushroom cultivation, a large amount of by-products, known as spent mushroom substrate (SMS), are left behind in open dumps where about 5 kg of SMS are generated for every kilogram of mushroom (Agaricus bisporus). Around 51 million tons of SMS are produced in the world every year. Hydrothermal carbonization (HTC) is a promising technology for the conversion of SMS into a rich carbon product, hydrochar. The hydrochar was synthesized in a hydrothermal reactor at a temperature of 180 °C for a reaction time of 1 h. The characterization of the SMS and its chars was done by FTIR, SEM, and TGA analysis. The FTIR analysis showed that aromatic and oxygen-rich functional groups are dominant on the hydrochar surface. It was noticed that the hydrochar had more visible pores compared to the SMS. The porous structure and oxygen functional groups of hydrochar probably influenced the improvement of adsorption performance, since the adsorption capacity of SMS for Cd2+ ions was 28 mg L-1, while for hydrochar it was 92 mg L-1. On the other hand, the thermal kinetic analysis has shown that hydrothermally treatment upgrades the combustion behavior of hydrochar. The kinetic parameters were determined by Kissinger and Ozawa methods. The hydrochar had notably lower activation energy compared to the SMS, which means that this hydrochar requires a smaller amount of energy to start combustion. The preliminary results show that HTC effectively transforms SMS into alternative solid biofuel and eco-friendly sorbent.

AB  - As an inert radioactive gas, 222Rn could be easily transported to the atmosphere via emanation, migration, or exhalation. Research measurements pointed out that 222Rn activity concentration changes during the winter and summer months, as well as during wet and dry season periods. Changes in radon concentration can affect the atmospheric electric field. At the boundary layer near the ground, short-lived daughters of 222Rn can be used as natural tracers in the atmosphere. In this work, factors controlling 222Rn pathways in the environment and its levels in soil gas and outdoor air are summarized. 222Rn has a short half-life of 3.82 days, but the dose rate due to radon and its radioactive progeny could be significant to the living beings. Epidemiological studies on humans pointed out that up to 14% of lung cancers are induced by exposure to low and moderate concentrations of radon. Animals that breed in ground holes have been exposed to the higher doses due to radiation present in soil air. During the years, different dose-effect models are developed for risk assessment on human and non-human biota. In this work are reviewed research results of 222Rn exposure of human and non-human biota. © 2020, ISB.

AB  - Radioactive materials released during the two most serious nuclear accidents in history, at Chernobyl and Fukushima, caused exceptionally significant contamination and perturbations of the environment. Among them, this paper focuses on the effects related to the atmospheric electricity (AE). Measurements of the most significant disturbances in the values of various AE parameters recorded near ground level are reviewed and the corresponding results are jointly evaluated. The Chernobyl and Fukushima events caused changes in the AE parameters both after long-distance transport (Chernobyl) and short-distance transport including re-suspension (Fukushima). The data indicates that the electrical conductivity of the air is more sensitive to the presence of airborne radioactivity than the atmospheric electric potential gradient (PG). PG, on the other hand, can be monitored more easily and its variation also reflects the vertical redistribution of radionuclides in the air due to their transport, deposition, and re-suspension from the ground. A brief overview of studies on atmospheric transport and deposition of radioactive clouds is given to facilitate the importance of considering the AE measurements in these subjects, and to incorporate those studies in interpreting the results of AE measurements. The AE measurements are particularly important in studying microphysical effects of enhanced radioactivity in the air where no other distance monitoring method exists, both for fair weather conditions wet conditions.

AB  - The chapter aims to summarize different remediation approaches of radionuclide pollutants in water and soil media carried out after decommissioning of nuclear installations worldwide. The attention was focused on different methods of remediation, e.g. natural attenuation, bioremediation, excavating and removing contaminated soil and in situ treatments. The results of radiological assessments of the influence of nuclear cycle facilities in the environment using different modelling approach of the radionuclides transport through the environmental medium are adopted as a useful tool in decision making process applied in remediation of contaminated areas. The current trend in development strategy to support the environmental decision systems for optimization of remediation actions is to use databases on environmental and managerial parameters and radioecological models for the prediction of the effectiveness of remediation measures.

AB  - New agar-based composite films with increasing Cu-carbonate and Cu-phosphate mineral phase content were prepared by in situ mineralization and solvent casting method. SEM and optical analysis revealed that Cu-carbonate phase had better compatibility with agar matrix than Cu-phosphate phase. Incorporation of both mineral phases improved mechanical and water vapor barrier properties of the obtained mineralized films, in concentration dependent manner. When 5 mM of carbonate precursor was incorporated into agar matrix, mechanical resistance was enchanced for 44% and water vapor barrier property for 40%. The release of Cu (II) was higher in acidic conditions for both mineralized composites and remained in the range of specific release limits for this metal. In addition, both mineralized composite films exhibited distinctive antimicrobial activity against Gram-negative (Escherichia coli) and Gram-positive (Staphylococcus aureus) bacteria. Overall, the Cu-carbonate and Cu-phosphate mineralized agar films showed potential to be used for food packaging materials, agriculture or medical purposes. © 2019 Elsevier Ltd

AB  - A valuable tool for external quality control that provides opportunity to improve analytical skills and techniques in the field of radioactivity measurements is participation in proficiency tests (PTs). In this work obtained results from the gamma spectrometry intercomparison for 15 laboratories conducted in May 1986 immediately after the Chernobyl accident for the lucerne sample contaminated with fission products: 140 Ba, 141 Ce, 144 Ce, 134 Cs, 137 Cs, 131 I, 103 Ru, 106 Ru, 95 Zr, are evaluated following the recommendations of the international standard ISO 13528:2005. Environmental radioactivity proficiency tests organized by International Atomic Energy Agency (IAEA) are designed to identify analytical problems, to help members states to maintain their accreditation and to provide knowledge and technology transfer in this area. The Analytical Laboratories for the Measurement of Environmental Radioactivity (ALMERA) is a world-wide network of analytical laboratories capable to analyzed radioactivity contents, coordinated by IAEA. Institute for the Application of Nuclear Energy (INEP), University of Belgrade, is an official member since 2013. Annual PTs are organized by ALMERA for the network laboratories using sets of different samples. Based on the PT proposition each result should pass accuracy and precision test to be awarded the status ‘Accepted’, otherwise it lies on the status ‘Warning’ or ‘Not Accepted’. INEP was participated in three worldwide open (in 2006, 2007 and 2011) and six (in a period 2012–2016) PTs organized by IAEA and ALMERA. Radionuclide activity concentrations in different environmental matrices were measured using gamma-ray spectrometer with high purity germanium (HPGe) detector. In IAEA worldwide open PTs among 61 results, 74 % were ‘Accepted’ and 26 % were ‘Not Accepted’.

abstract = "A valuable tool for external quality control that provides opportunity to improve analytical skills and techniques in the field of radioactivity measurements is participation in proficiency tests (PTs). In this work obtained results from the gamma spectrometry intercomparison for 15 laboratories conducted in May 1986 immediately after the Chernobyl accident for the lucerne sample contaminated with fission products: 140 Ba, 141 Ce, 144 Ce, 134 Cs, 137 Cs, 131 I, 103 Ru, 106 Ru, 95 Zr, are evaluated following the recommendations of the international standard ISO 13528:2005. Environmental radioactivity proficiency tests organized by International Atomic Energy Agency (IAEA) are designed to identify analytical problems, to help members states to maintain their accreditation and to provide knowledge and technology transfer in this area. The Analytical Laboratories for the Measurement of Environmental Radioactivity (ALMERA) is a world-wide network of analytical laboratories capable to analyzed radioactivity contents, coordinated by IAEA. Institute for the Application of Nuclear Energy (INEP), University of Belgrade, is an official member since 2013. Annual PTs are organized by ALMERA for the network laboratories using sets of different samples. Based on the PT proposition each result should pass accuracy and precision test to be awarded the status ‘Accepted’, otherwise it lies on the status ‘Warning’ or ‘Not Accepted’. INEP was participated in three worldwide open (in 2006, 2007 and 2011) and six (in a period 2012–2016) PTs organized by IAEA and ALMERA. Radionuclide activity concentrations in different environmental matrices were measured using gamma-ray spectrometer with high purity germanium (HPGe) detector. In IAEA worldwide open PTs among 61 results, 74 % were ‘Accepted’ and 26 % were ‘Not Accepted’. In ALMERA network PTs among 70 results, 84.3 % were ‘Accepted’, 4.3 % were ‘Warning’, 11.4 % were ‘Not Accepted’. PT exercises are the best way to identify gaps and problems areas where further development is needed.",

AB  - The main focus of this study was to assess radiation exposure to human and non-human biota due to natural radionuclides in soil of the Serbian capital. For the first time, ERICA tool was employed for calculation of gamma dose rates to non-human biota in this area. In analyzed soils, the mean values of Ra-226, Th-232 and K-40 specific activities were found to be 35, 43 and 490 Bq kg(-1), respectively. The distribution of analyzed natural radionuclides in soils was discussed in respect to its statistically significant correlations with sand, silt, clay, carbonates, cation exchange capacity and pH value. The annual outdoor effective dose rates to the population varied from 48 to 98 mu Sv, and the total dose rates to terrestrial biota, calculated by ERICA tool, varied from 9.84 x 10(-2) mu Gy h(-1) (for tree) to 5.54 x 10(+0) mu Gy h(-1) (for lichen and bryophytes). The results obtained could serve as a baseline data for the assessment of possible anthropogenic enhancement of the total dose rate to human and non-human biota of the study area.

AB  - Thousands of samples of wild mushrooms from the territory of Serbia were analyzed to
determine activity concentrations of 137Cs by using gamma spectrometry in the Institute
for the Application of Nuclear Energy – INEP, during the period of thirty years after the
accident in nuclear power plant 'Lenin' in Chernobyl. Statistically analyzed results were
presented in this work. It is known that mushrooms are good bioindicators of radioactive
pollution. The level of radiocesium uptake depends on the mushrooms species, but also
of their treatment (drying, marinating, pickling). The highest activity concentration was
2390 Bq kg-1 for 137Cs (fresh weight) in 1986 in Morchella conica, while activity
concentrations 137Cs in samples collected 2015 were less than 0.1 Bq kg-1. As expected, activity concentrations of 137Cs in mushrooms decreased during the years, with some
exceptions from this trend (e.g. activity concentration of 137Cs in Boletus edulis collected
in 2002 was 1004 Bq kg-1 (dry weight)).

AB  - The need for reliable assessments of soil erosion rates in Serbia has directed attention to the potential for using Cs-137 measurements to derive estimates of soil redistribution rates. Since, to date, this approach has not been applied in southeastern Serbia, a reconnaissance study was undertaken to confirm its viability. The need to take account of the occurrence of substantial Chernobyl fallout was seen as a potential problem. Samples for Cs-137 measurement were collected from a zone of uncultivated soils in the watersheds of Pcinja and South Morava Rivers, an area with known high soil erosion rates. Two theoretical conversion models, the profile distribution (PD) model and diffusion and migration (D and M) model were used to derive estimates of soil erosion and deposition rates from the Cs-137 measurements. The estimates of soil redistribution rates derived by using the PD and D and M models were found to differ substantially and this difference was ascribed to the assumptions of the simpler PD model that cause it to overestimate rates of soil loss. The results provided by the D and M model were judged to more reliable. (C) 2016 Elsevier Ltd. All rights reserved.

AB  - The area of southeastern Serbia, the Pinja and South Morava River Basins, is under the influence of very strong erosion, and the aim of this study was to investigate the vertical and spatial distribution of the Cs-137 in the eroded soils of this area. Vertical soil profiles were collected with 5-cm increments from the uppermost layer down to 20, 25, 30, 40, and 50 cm of depth, depending on the thickness of the soil layers, i.e., down to the underlying parent rocks. Measurements of Cs-137 activity concentration were performed by using the HPGe gamma-ray spectrometer ORTEC-AMETEK (34 % relative efficiency and high resolution 1.65 keV at 1.33 MeV for Co-60), from its gamma-ray line at 661.2 keV. The mean Cs-137 activity concentration across all 18 soil profiles (for all soil layers) was found to be 20 Bq kg(-1). In the greatest number of soil profiles, the Cs-137 activity concentration was generally highest in the first soil layer (0-5 cm) and decreased with soil depth, while in a few soil profiles, the peak of either the Cs-137 activity concentration occurred in the second soil layer (5-10 cm) or the Cs-137 activity concentration was almost equal throughout the entire soil profile. The mean Cs-137 activity concentration in the first soil layer (0-5 cm) was found to be 61 Bq kg(-1), and the high coefficient of variation of 92 % pointed out high spatial variability and large range of the Cs-137 activity concentrations in the study area. The obtained results indicate that in the greatest number of soil profiles, Cs-137 is present in the upper layers, with concentration decreasing with depth, as is typical in uncultivated soil. Its spatial distribution was very uneven among the surface soil layers of the investigated sites. One of the main reasons for such pattern of Cs-137 in the study area may be soil erosion. Additional investigations which would support this hypothesis are required.

AB  - Metallic materials, such as Co-Cr-Mo alloys, are exposed to aggressive conditions in the oral cavity that represents an ideal environment for metallic ion release and biodegradation. The metallic ions released from dental materials can cause local and/or systemic adverse effects in the human body. Therefore, dental materials are required to possess appropriate mechanical, physical, chemical and biological properties. The biocompatibility of metallic materials is very important for dental applications. Accordingly, the aim of this study was to examine metallic ion release and cytotoxicity of Co-30Cr-5Mo cast alloy as the initial phase of biocompatibility evaluation. Determination of the viability of human (MRC-5) and animal (L929) fibroblast cells were conducted using three in vitro test methods: the colorimetric methyl-thiazol-tetrazolium (MTT) test, the dye exclusion test (DET) and the agar diffusion test (ADT). Furthermore, the morphology and growth of the cells were analyzed using scanning electron microscopy (SEM). The obtained results indicated that Co-30Cr-5Mo alloy did not release harmful elements in concentrations high enough to have detrimental effects on human and animal fibroblasts under the given experimental conditions. Moreover, the fibroblast cells showed good adhesion on the surface of the Co-30Cr-5Mo alloy. Therefore, it could be concluded that Co-30Cr-5Mo alloy is a biocompatible material that could be safely used in dentistry.

Therefore, dental materials are required to possess appropriate mechanical, physical, chemical and biological properties. The biocompatibility of metallic materials is very important for dental applications. Accordingly, the aim of this study was to examine metallic ion release and cytotoxicity of Co-30Cr-5Mo cast alloy as the initial phase of biocompatibility evaluation. Determination of the viability of human (MRC-5) and animal (L929) fibroblast cells were conducted using three in vitro test methods: the colorimetric methyl-thiazol-tetrazolium (MTT) test, the dye exclusion test (DET) and the agar diffusion test (ADT). Furthermore, the morphology and growth of the cells were analyzed using scanning electron microscopy (SEM). The obtained results indicated that Co-30Cr-5Mo alloy did not release harmful elements in concentrations high enough to have detrimental effects on human and animal fibroblasts under the given experimental conditions. Moreover, the fibroblast cells showed good adhesion on the surface of the Co-30Cr-5Mo alloy. Therefore, it could be concluded that Co-30Cr-5Mo alloy is a biocompatible material that could be safely used in dentistry.",

AB  - The 137Cs activity concentrations in six undisturbed soil profiles collected
during 2013 in the basin of Pčinja River, southeastern Serbia, were
determined gamma-ray spectrometrically. Average value of six undisturbed
soil profiles by layers was calculated and vertical distribution of 137Cs
activity concentration at 5 cm interval samples was shown by average
profile. The 137Cs activity concentrations varied between 0.29 and 70.9 Bq
kg-1 with a mean of 10.7 Bq kg-1. Even 27 years after Chernobyl accident
74% of deposited 137Cs was found in the first 20 cm of the soil.

AB  - Accurate monitoring of indoor mass concentrations of particulate matter is very important for health risk assessment as people in developed countries spend approximately 90% of their time indoors. The direct reading, aerosol monitoring device, Turnkey, OSIRIS Particle Monitor (Model 2315) and the European reference low volume sampler, LVS3 (Sven/Leckel LVS3) with size-selective inlets for PM10 and PM2.5 fractions were used to assess the comparability of available optical and gravimetric methods for particulate matter characterization in indoor air. Simultaneous 24-hour samples were collected in an indoor environment for 60 sampling periods in the town of Bor, Serbia. The 24-hour mean PM10 levels from the OSIRIS monitor were well correlated with the LVS3 levels (R-2=0.87) and did not show statistically significant bias. The 24-hour mean PM2.5 levels from the OSIRIS monitor were moderately correlated with the LVS3 levels (R-2=0.71), but show statistically significant bias. The results suggest that the OSIRIS monitor provides sufficiently accurate measurements for PM10. The OSIRIS monitor under-estimated the indoor PM10 concentrations by approximately 12%, relative to the reference LVS3 sampler. The accuracy of PM10 measurements could be further improved through empirical adjustment. For the fine fraction of particulate matter, PM2.5, it was found that the OSIRIS monitor underestimated indoor concentrations by approximately 63%, relative to the reference LVS3 sampler. This could lead to exposure misclassification in health effects studies relying on PM2.5 measurements collected with this instrument in indoor environments. (C) 2012 Elsevier Ltd.
